set pastetoggle not working

Question

My vim setup( https://github.com/aaronjorbin/.vim ) contains set pastetoggle=<F2> yet fn+F2 (when vim is running in terminal) causes vim to enter insert mode and output a Q on it's own line (same behavior when I am already in insert mode). This is the same if I am working on my local machine or if I have sshed into another server.

In iterm2, nothing happens when I am in normal or visual mode. When I am in insert mode, <F2> is inserted.

My config works perfectly well on my mac mini and linux netbook, but this is throwing me for a loop.

Answer 1

This is likely due to your TERM type being set to something other than xterm xterm-color or xterm-256color. I had mine set to linux for some reason I can't remember. This caused the function keys to send escape sequences instead of being interpreted as function key presses. ie- F2 was sending ^[OQ instead of <F2>.

If you need that terminal type you can change your .vimrc to use the key you want by pressing <ctrl-v><F2> in place of typing <F2>

The easier fix is of course to just change your terminal type to something that allows vim to work without jumping through hoops.
