Description

Many vim distros like LazyVim or NvChad and Doom Emacs or even Helix have a Which-Key popup for extra keybinds.
It's extremely useful and you could even have an optional delay so you can complete the combination before it opens, you have a visual UI which tell you which key you can press to open which many for example you press W and then V to go to window settings and split it vertically. I'm currently using Zed as my main text editor and would love to have this feature as it helps a lot and makes it feel really like a Vim alternative.

This could become a crucial part of the Vim workflow and could be really essential to the Zed experience.
Many editors have it as a plugin although some have it built-in, once Zed gets plugin support it might even be implemented through a plugin but I like the native way more

If applicable, add mockups / screenshots to help present your vision of the feature

These images aren't mine, I just found them on Google but I've tried all of these implementations of which-key.
This might just seem like the command line when pressing : in Zed but it's very different when actually using
