The autocommand I would like to run is

au CmdlineModeEnter * wall

except that CmdlineModeEnter does not exist. I used to have a mapping defined like

nnoremap : :wall<CR>:

which worked fine except that the ":wall" flashing up was visible and distracting. Any ideas?

function! CmdlineEnter()
    silent! wall
    call feedkeys(":", 'n')

noremap <silent> : :call CmdlineEnter()<CR>

@Owen strictly speaking, Ex mode is what you enter with Q, not :: : enters Command-line mode (as do / and ?). – accolade Jun 17 '11 at 23:14
Thank you! That works! – Owen Jun 20 '11 at 20:46
Owen added silent! to suppress warnings. – BloodPhilia Jun 20 '11 at 20:56

Does this help?

nnoremap <silent> : :wall<CR>:


:help :map-<silent>

Yes, it does make the ":wall" go away... unfortunately it also hides the leading : until I type the next char ;). Oh well I think I'm just too picky. – Owen Jun 5 '11 at 6:20
