Ctrl+D in the editor duplicates the selected block or the current line when no block is selected.

If the cursor is between the parentheses of a method call, pressing Ctrl+P brings up a list of valid parameters.

Use Ctrl+Shift+F7 (Edit | Find | Highlight Usages in File) to quickly highlight usages of some variable in the current file.
Use F3 and Shift+F3 keys to navigate through highlighted usages.
