How `which_key_use_floating_win' works?

[srustamo]

I try to set it to 1 but can't get popup on vim 8.2 in terminal.

Any docs on its use?

[rene-descartes2021]

A guess is that g:which_key_use_floating_win has to be set prior to the plugin being loaded. As otherwise s:use_popup in autoload/which-key/window.vim won't be set.

Documentation is in :help vim-which-key.

Re-open if there is still issue.
