Keyboard Up/Down Zoom In/Out

[ivbillusa]

Version 4.62 64b Win 10.

I'm surprised you haven't done this.

I use the LEFT and RIGHT arrows to move from image to image in a folder/directory,
and it would be nice to be able to use the UP and DOWN arrows
to Zoom IN and OUT.
It should reset to 100% (or whatever the default is) on each next image.

Or allow the keyboard to be programmed to whatever keypress-functions we want.
Single or multiple available functions per keypress.

[IfThenElse]

Up and Down arrows are used to scroll the zoomed image up and down,

Is there a problem using the hotkeys that are already provided for zoom?

i.e.
- Zoom out
+ Zoom in
= Zoom in

From the view menu, see Display Options. If the image is larger than the window, left/right up/down home/end will scroll the image within the window.
If fit image to window is set, left/right will scroll images in the same folder (if that option is enabled).
