If you're moving to a separate terminal to test, that sounds like
another keystroke or mouse-movement. You could set up vi/vim to
autosave on suspension, then use one function key to suspend back to
your shell prompt, run your test, and use a shell alias to get back
to your edit session.
VIM settings:
set autowrite
imap #5 <ESC>:suspend<CR>
Shell aliases (works for bash/zsh, syntax for tcsh is different):
alias 1='%1'
alias 2='%2'
alias 3='%3'
alias 4='%4'
alias 5='%5'
alias 6='%6'
alias 7='%7'
alias 8='%8'
alias 9='%9'
This way, you can restart a suspended job without having to type a dopey
percent sign first. Here are some other VIM mappings I've found useful.
I hate using the shift key unless it's essential, so to indent/deindent:
map ; >>
map = <<
It's easier for me to see context when the cursor is around the middle
of the screen:
map q z.
Sometimes I like a column ruler just for a second or two. Press 'E' to
see it, then 'u':
map E o<Esc>i....+....1....+....2....+....3....+....4....+....5....+....6....+....7....+<Esc>
I like my paragraphs ragged-right, around 75 columns long. This lets me
reformat whatever paragraph I'm in by pressing 'v':
map v }jmbk{ma}:'a,.!fmt -1^V|fmt -75<CR>'b
The "^V" is an actual control character, so you have to hit Ctrl-V twice
to put it in your .vimrc file. My .vimrc file is here:
