[Feature Request] Tool Keybindings: allow for other keys than modifier keys or mouse keys

[nagychris]

What feature or change would you like to see made?

I would like to use other keybindings like SHIFT+A+leftclick to activate a tool.
However, to my current knowledge and what I saw in the docs / code of cornerstone3d (https://github.com/cornerstonejs/cornerstone3D/blob/bb71a514486a519a45468b1f474b5c2c0bb25575/packages/tools/src/enums/ToolBindings.ts), this is currently not possible as the ToolBindings only support mouse / modifier keys.

It would be amazing to have a flexible third parameter to pass to the ToolGroup.setToolActive (i.e., https://github.com/cornerstonejs/cornerstone3D/blob/bb71a514486a519a45468b1f474b5c2c0bb25575/packages/tools/src/store/ToolGroupManager/ToolGroup.ts#L346C10-L346C) so that it also supports to pass another flexible key (e.g. listening to the keydown event - see https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/code)

Why should we prioritize this feature?

Would remove the need to implement this feature on my own, and makes the library tools more flexible to use.

@sedghi Correct me if I am wrong, but I can only see modifier keys and mouse keys there, but no letter keys like A or Z...

I already tried to implement the feature on my own, by just listening to keydown and keyup events, and setting the respective tool active / passive, so that I can use the tool as long as the buttons are pressed. But it doesn't work somehow, probably because cornerstone3D handles all the mouse events on the viewport and stops propagation?
