[Feature Request]: Node Source Badge / Node ID Hotkey or OnKeyDown

### Is there an existing issue for this?

- [x] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?

Hey there,

this is just a qol feature I wished was a thing quite often.
Especially dense workflows, where nodes are packed without distance and/or minimized the display of node ID and source node pack together with all the z-fighting does not look good, so I keep it off by default.
But it takes a lot of steps to turn on and then off again, whenever I need to check something for a second.

Right now the procedure is:
1. Go to **Settings**
2. Click on **Lite Graph**
3. Scroll down **Node Source Badge Mode**
4. Click on the dropdown menu
5. Select **Show All/Never**
6. Exit menu

### Proposed workflow

The feature would be the addition of a configurable keyboard shortcut to function as a quick toggle for this. Alternatively, handling it as an OnKeyDown option *(like holding down the alt-key in a lot of diablo-esque rpgs works to show loot while pressed)*

### Additional information

Thank you for your time and effort!
