Use the following to list your buffers.
nnoremap <m-:> :ls\|sleep<CR><CR>
Press Alt-: to show the results of
:ls for one second. Pressing Alt-: 3 times will show the
:ls listing for 3 seconds.
You can also hold down Alt-: to show the file list continuously, then press Ctrl-c when you're done. This can be very useful when working with many files.
I'll try this for some days:
map <M-:> :<c-u>ls!<Bar>sleep <c-r>=v:count1<CR><CR><CR>
" alt-; display buffer list for 3 seconds nnoremap <m-;> :ls<Bar>3sleep<CR><CR>
It should be noted that if 'lazyredraw' isn't set, the original mapping will cause the entire display to be refreshed for each <m-:> combination.
