Zooming and Panning with the new kitty image backend

[terencode]

I'm using kitty and I can't find how to pan and zoom with the new image backend.

agh, yes of course - i forgot to add the instructions for how to zoom and such to the help page. i'll do that tonight, thanks for pointing it out. for reference, it's:

z to enter fill-screen
o to zoom in
O to zoom out
shift+{h,j,k,l} to pan while zoomed without changing the page

Ah thank you! I just tried it and it's working indeed, great work! I have a few remarks:

• It is not possible to zoom in more than the width of the terminal. Is this to be expected because of being in fill-screen mode ?

• Same issue when you zoom out, but this time with the height of the terminal. However, contrary to zooming in, you can keep zooming out, but it will result on the page being progressively cropped right-to-left.

• I don't know how feasible it would be, but what about also having ctrl+scroll-wheel for zooming in/out? Or maybe configurable shortcuts in general?

That's just a limitation of the current implementation. I should probably make a new issue to track implementation of zooming in past fill-width specifically

Ah! You're right, thanks for catching that. I'll make an issue for that and fix it.

I think that's fairly feasible, and also a reasonable extension of the current controls.

Configurable shortcuts, on the other hand, are a much bigger and more in-depth ask. If you'd like to make an issue specifically asking for configurable shortcuts to see how interested other users are in this feature, I would appreciate that. I can use that to gauge what would be the most helpful to spend my time on,

Closing this since the important sub-issues are now noted in separate issues
