Home, sweet Home! This is the interface you'll have for most of the time. As a rule of thumb, left mouse button (LMB) will do standard actions, while right mouse button (RMB) will go into relevant setup/option interface of some sort. For example, LMB on the Zoom button will let you select an area to zoom into. RMB on the Zoom button will allow to to pick the degree of zoom. So, if you use the LMB in the open area, you will draw with the selected tools. RMB will hide and show the Home frame. You can also use "Space" for this. Oh, and if you ever get stuck in an interface bit where you want to exit, you can just RMB over the open area, or press "Space".
Now, onto the specifics!
There's three basic elements to the Home interface: Your color palette, the drawing tools, and the ink types.
The color palette consists of the colors you have easy access to. You can change any of these colors by right-clicking it, then selecting a replacement color. The first color, all by itself, is your "zero clear" color - that is, transparent. If you change this, you change the color of nothingness. Next to that are the handy bunch of colors that you want easy access to. Some of them have additional roles when it comes to in-betweening, but that's a matter for later. You can see your currently selected color on the far right under the Etc. section. Below this is a palette segment. You're allowed a maximum of 256 colors at any one time, and you can grab a section or two of that 256 to have easy access to, like the colors above. LMB will select a color, and RMB will open up the wondrous Palette interface, where you can access, select, and manipulate your 256-color palette (as well as the smaller palette segments and other colors) to your heart's content. It's a very thorough part of the program, and I'll get to it later.
So, on the left you have your drawing tools. From simple mouse-drawn lines to spline shapes and polygons to fill and separate, it determines the shapes that you draw and how. You can have six at your immediate disposal, and you can change which ones are there (as well as the advanced options for them) by using the RMB. There's a long list of them, and they all have descriptions. Check 'em out, and see what kinda stuff you can find.
You may notice some recurring options among drawing tools. Things like Closed, Fill, and Tween are shared (on or off) among the tools which use 'em. Fill (fills the shape with a color) and Tween (used for animating between two different shapes) even have indicators on the Home frame: the F and T under the Etc. section.
Ink types, on the right side, determine how the ink affects the drawing. Like drawing tools, you can have six available at any one time, and you cna change 'em out/adjust the options by using the RMB. There's a great deal of variety, again, from opaque and transparent colors to softening sharpening to making pixels move or scramble to gradients of different types and directions. Try 'em out, and see what you can find.
Equally important when it comes to animation is the frame control, sitting beneath the color palette. You can use this to move through your frames, as well as check the animation. Left-to-right you have First Frame (which you can use the up arrow to get to), Previous Frame (also left arrow), Current Frame, Next Frame (right arrow), Animate (you can use down arrow for this), and Last Frame. If you click LMB or RMB on the current frame number display, you enter into the Frames interface, where you can adjust your current frame, your maximum frames (you can add or subtract or even multiply the current frames by 2, 3, or 5) and segment-based animation control. Which is a matter for later. But this is where you come to adjust you frame count. You can also insert a single frame by pressing the "Insert" key from the Home frame, and delete one with the "Delete" key.
For what's left over, I'll go over the Etc. section: On top, you have your brush size and current color. LMB on the brush size will switch between one pixel and many pixels. RMB will determine how many pixels "many pixels" is. Either LBM or RMB on the current color will open up the Palette interface.
Beneath this are four boxes: F means fill a shape, T is for shape-tweening, M refers to a color mask, and I have no idea what the K stands for.
Woof... I hope that's a little helpful to start, even though it's basic stuff. I'll get to the more confusing bits later...
Awesome! Let's see if I can't cover some of the more animation-based aspects, then...
Starting with the options in the menu bar:
ANIMATOR Most of the stuff here can be accessed with the RMB on the home area below: palette, drawing tools, ink effects, etc. "Browse Flics" is simply a way to look through the thumbnails of the Flic files that you've saved, "Titling" I think has to do with adding scrolling text, or something, and "Optics" involves moving, rotating and resizing a two-dimensional image in a 3D plain, which, while interesting, has limited application.
FLIC A Flic is your current animation. The file you're working on. "New" will through away the frames and all, but keep your palette, your settings, and anything you have saved in other means. "Reset" will throw everything out and revert back to the default settings. There's also a way to change what the default is, if you feel it necessary. You can load and save flics here, as well as do things like attach two flics to one another, overlay one on top of another, save one backwards, and some other stuff.
PIC A single frame; you can save and load a Pic as a GIF along with its palette data. Of the other options, "Clear" will clear the screen, "Restore" will restore it to what it looked like when you first entered that frame (using the frame controls), "Apply Ink" will apply the current ink effect to the entire frame (as though covering the whole thing with a filled rectangle), "Separate" will replace whatever color you click on with the current color and ink effect (this one's also available under the drawing tools, and I wish more programs would allow me to do this), and "View"... um, views the frame.
CEL A Cel is the equivalent of the modern-day clipboard. You can clip a section of the scene, move it around, stretch it, turn it, and paste it where you please. Also, if Tween is turned on (the T in the lower-right corner*), you can make a Cel move automatically from one position to another, pasting itself automatically on each frame in between in the specified range of frames. You can also, of course, load and save them as you desire. They aren't saved with palette data, but they'll do their best to fit their colors using the current palette. I'm sure there's a lot more potential to Cels than I've ever realized, particularly if one were to use 'em in a traditional sense.
*Many menu commands and other things will make use of the "Tween" option. If you want something to apply to a single frame only, make sure the T is off.
TRACE This menu contains most of the more traditional animation techniques, though I'm not really sure what a lot of the options here do. But there's some good stuff here. First of all, "Blue" refers to the first color of the easy-access color palette, which, by default, is blue. This blue is used when you make a guideline frame, and can be erased with a single command ("Unblue Frame"). The second color, by default green, is also used as a guide.
The most useful command I know of here is "Insert Tween", which will create a new frame between the frame you're on and the next frame. This frame will show what's drawn on both frames using the blue and green colors. You can then draw an appropriate in-between and erase the guides using "Erase Guides". Useful stuff.
Unfortunately, I have little to no idea what most of the other commands here do. Sorry.
SWAP This is used to create a little piece of space outside of your animation. Simply choose "Clip", and the current frame will become your swap space. You can use "Trade" to switch between the two spaces, "Paste" to overwrite your current frame with the swap space, "View" to simply see what's on the space, and "Release" to get rid of the swap space. You can also use the "Scrape" ink effect to draw through to the swap space, if you so wish.
EXTRA Various things are here, such as masks, grids, macros, settings, and the like. I don't remember exactly how to set up masks and grids and such, but it shouldn't be too difficult. Macros are fairly interesting (I was always amused that the last thing to happen in any recorded macro was the mouse going up into the menu and hitting "End Record"), but I'm not exactly sure how useful they can be. The program does come with a macro that shows off the "Optics" options fairly well, as well as color cycling, but that's all of limited use.
...And that's the menu commands, albeit a little incomplete. Hopefully it's still helpful.
