Function description/docs auto pop up in Normal mode

[mangkoran]

Hi all! Currently I am still learning about Helix, coming from Neovim and (Doom) Emacs.

I noticed that Helix has LSP function description/docs pop up (not sure what it is called), but only in Insert mode. How can I have this in Normal mode, so that the function description would automatically popped up if I hover the function, like I have with Doom Emacs? I have asked around in Matrix and clement-42 pointed that Helix has SPC k to display documentation for item under cursor, but it seems this took more space compared to the pop up in Insert mode. Thank you!

Edit: What I would like to have is documentation to auto pop up/show on hover in Normal mode. Helix already has it but it need manual invoke (SPC k), not auto pop up.

Same! This would be very useful as you spend a lot of time reading code, not just writing it.

The command to bind for that is signature_help
