Description

I'm running the Tracy UI on Linux, but remotely: my local machine is a Mac and I'm using a remote desktop solution to use my Linux machine.

At least in the default setup that I'm on, Macs have only 1 mouse button, so I can't easily use Tracy features relying on the right and middle clicks. Mac OS has a notion of secondary click, but I haven't been able to use that with Tracy UI in remote desktop. I'm not able to pinpoint where exactly the problem was (in Tracy, or in remote desktop). The higher level point that I would like to convey is that it would be really useful to have all Tracy features accessible with only 1 mouse button.

As a simple step, might it be possible to at least let Tracy accept some modifier key + left click as substitute for right and middle click?

Research direction
Investigate how mouse input is currently handled in the Tracy UI. The UI likely uses ImGui; find the relevant input event handling code (e.g., in files like 'imgui impl xxx.cpp' or custom input handling). Look for existing ways to remap mouse buttons. Then implement a modifier key (e.g., Ctrl or Shift) combined with left click to emulate right and middle clicks. Ensure the change is optional and does not break existing functionality.
