Since I use this item a lot it would be very nice if this item could be reached via a shortcut. Thanks in advance!
Yes, customizable keyboard shortcuts, and/or adding new ones where missing, is definitely needed. Thankfully, this particular functionality is already exposed in the menu, which allows it to already be accessed without the mouse:
- Windows: F10: Activate the menu bar: You can then enter "T" to get to the "Tools" menu
- macOS: Command + Shift + /: You can then search for "Adjust" or "Capture", use the cursor down and then hit Enter/Return.
