Ability to Remap Pan Shortcut to "Alt + Shift + Left Click" instead of "Middle Click"

Unity Engine
1

I recently switch from Maya to Blender, and I love that I can easily pan around with “Alt+Shift+Left Click” instead of the standard “Middle Click” pan. Many computer mice have awkward middle click buttons, and I’ve found that the “Alt+Shift+Left Click” shortcut in Blender is far easier for me to use.

Currently “Shortcuts” in Unity only allow keyboard input and there is no “3D Viewport/Pan” command to replace. It’d be awesome if Unity could add a “3D Viewport/Pan” command and allow mouse input to be combined with keys in Shortcuts.

I created an AutoHotkey script that maps “Alt+Shift+Left Click” to a Middle Click hold, but I can’t get it to feel as smooth as Unity’s Middle Click pan, which is why I made this feature request. If you want to run the script for yourselves, save the attached text file as a .ahk and run it with AutoHotkey. Thanks!

Just did some more research and found some pre-existing solutions to my problem: Unity - Manual: Scene view navigation

I guess you can press “Q” or use “Alt+Ctrl+Left Click” to use the Move/Hand tool, but it’d still be nice to have the option to remap it.

bump. still looking for a way to rebind controls for pan and zoom

alright, I did some refinement with chatgpt and got a working script for the controls I wanted (pan: shift + alt + left click, zoom: ctrl + alt + left click. just like in Blender). if someone wants to use their own controls they can either dive into the code or ask chatgpt to change it. sensitivity is adjusted with the ‘5f’ and ‘.002f’ values
