let speed bar recognize scala file perfectly
1. create ~/.ctags as follows(notice for regexps I used ^[ \t] to excactly match):
--langdef=Scala
--langmap=Scala:.scala
--regex-Scala=/^[ \t]*class[ \t]*([a-zA-Z0-9_]+)/class \1/c,classes/
--regex-Scala=/^[ \t]*object[ \t]*([a-zA-Z0-9_]+)/object \1/o,objects/
--regex-scala=/^[ \t]*trait[ \t]*([a-zA-Z0-9_]+)/trait \1/t,traits/
--regex-Scala=/^[ \t]*case[ \t]*class[ \t]*([a-zA-Z0-9_]+)/case class \1/m,case-classes/
--regex-Scala=/^[ \t]*abstract[ \t]*class[ \t]*([a-zA-Z0-9_]+)/abstract class \1/a,abstract-classes/
--regex-Scala=/^[^\*\/]*def[ \t]*([a-zA-Z0-9_]+)[ \t]*.*[:=]/f \1/f,functions/
#--regex-Scala=/^[^\*\/]*val[ \t]*([a-zA-Z0-9_]+)[ \t]*[:=]/\1/V,values/

AutoHotkey script to map Caps Lock to Escape when it's pressed on its own and Ctrl when used in combination with another key, à la Steve Losh. Adapted from one that does something similar with the Ctrl Key on the Vim Tips Wiki (http://vim.wikia.com/wiki/Map_caps_lock_to_escape_in_Windows?oldid=32281). (Plus contribs from @randy909 & @mmikeww.)
g_LastCtrlKeyDownTime := 0
g_AbortSendEsc := false
g_ControlRepeatDetected := false
*CapsLock::
if (g_ControlRepeatDetected)
{
return
}
