Awesome @ArtemDrozdov. I haven't tried it out yet, just looked over the code, but it seems sound to me! I have a few suggestions and a reorganization request below though.

Could you put these in a Constants sub-module at the top of the file?

What's the reason you pass in a zoomAction instead of just passing in the value directly?

What do you mean by
instead of just passing in the value directly
Can't get your point.

Looking closer, I guess you can't pass in currentZoomValue +. zoomStep) directly instead of ZoomIn because you need currentZoomValue. But you could do zoomEffect(state, zoom => zoom +. zoomStep).

You can use Utility.IntEx.clamp for this. It would be significantly more readable I think.

I don't see any reason for these and the effect to need to live in VimStoreConnector. Could you move it to CommandStoreConnector instead (unless there's a reason I don't see)?

Oh, CI fails on an unused variable warning. That should be a quick fix though. |
Added keybindings for zoom in, zoom out and zoom reset according #1423 issue.
I checked zooming behavior in VSCode and they have next logic: default value is 0, minimum is -8 and maximum is 9. Zooming step is 1 which equals to 20%.
Short summary what was done in this PR:
Minimum value for zooming is 0 because on lower values there is no changes in UI.
And probably there should be some logic to process Cmd + = on Mac and Ctrl + = on Linux/Windows for example. Because with current implementation both of those combinations are working on Mac.
Would love to hear any comments and suggestion!
