Is there a somewhat orthodox way to enter ex mode faster, like with a single key stroke, instead of hitting shift-; for ':'? Why was that character ever chosen for such a frequently accessed mode? Often enough to be annoying I'll accidentally miss the shift key, start typing an ex command, and find I have a lot to undo. Thanks for your suggestions. :)
Set up your own mapping. e.g.
nmap <Space> :
Now spacebar in Normal mode takes you to the command line. However personally I don't find :
hard to type. You get used to it after a few months of Vimming.
rather than making a quick macro just to enter : you might want to automate whatever you're rushing to do all the time. Little tricks like this add up.
I find double slash as an easy leader. (a lot of plugins map single \ )
eg I have
nnoremap \\t :vert stag <-- opens tag of current word in vertical window
nnoremap \\g :vimgrep */ <-- searches code tree for word under cursor
nnoremap \\w :w
etc
Typing ':' doesn't put you into ex mode, it puts you into command mode. I'm not sure if this is a default keybinding, but "Q" puts me into ex mode.
As for a faster way of getting into command mode, it doesn't get much faster than a single keystroke. I would recommend just taking a little bit of time to get used to it.
