Anyone knows how to configure vim so that line number can show/hide by F10?
Now I'm typing set nu/nonu
,which is not convenient...
map <F10> :set number!
<- Should do the trick (AFAIK, the ! at the end makes it a toggle, instead of an always-on).
EDIT: Apologies, I forgot an important note (which you may have already known, but it was inconsiderate of me to forget): To make this persistent, add this line to your .vimrc
file.
Take a look at this page for reference, and this SO question for more.
