Vim binding, shell interactive mode

[leonclx]

In my .lfrc, if I " set shell zsh set shellopts '-eu' " and then open a text file from lf with vim, the vim remapping "map :w" doesn't work. It's a remap to write the file by pressing esc twice.
Changing my .lfrc to " set shell zsh set shellopts '-i' " causes the esc-esc remap to work, but closing a text file in vim with ZZ makes the lf window disappear while lf still runs somewhere in the background. There's also remapping commands (qwertz -> colemak) in my .vimrc, they seem to always work. /etc/vimrc and .vimrc are identical.

Furthermore if I open lf by typing "lf" into a terminal with shellopts '-eu', esc-esc works. If I open lf by typing "foot lf" into a terminal, esc-esc doesn't work. Sorry if this isn't the right place to ask, any help would be appreciated.
