Using Logitech MX Master 4 and MX Keys S simultaneously

Configuration Help & General Discussion

I tried assigning each shortcut combination sepparetely, but “sometimes” this method fails because BTT will not listen to the shortcut repeatedly

not sure if would be best to set a chain of “if key is being pressed” for each key combination of F keys + currently pressed modifiers

22

if you still have these active, you might need to delete them when using the method described above - otherwise they might catch your modifier clicks before the other one can react

I'll check why they might not allow re-triggering, this could be a bug!

that's normal as this is the only trigger set up in BTT - which should handle all modifier keys.

In what app are you using these F keys? (It could be that app does not like programatically generated keyboard events)

27

Photoshop and Figma (desktop version)

Finder

it doesn't work in any app really

Unfortunately I can not reproduce this here, I just did some more tests in Photoshop (e.g. the Fill command which defaults to Shift+F5 on my machine) but it all seems to work fine.

Which version of macOS are you currently running? (I'm on 26.2)

Do you have some other mouse / keyboard related apps running that might interfere?

29

Yeah, I’m also using the latest version of MacOs, 26.2. Also the latest version of BTT.
I don’t know why it doesn’t work to be honest. BTT is the ONLY shortcut tool currently installed on my computer. Andreas, could you help me figure this out somehow? I have extensively tried workarounds, and I imagine that it’s possible that with your aid I might be able to fix this in minutes

Just wanted to say thank you @Andreas_Hegenberg. For your reactivity, availability and the great support you provide for your tool! I am aware of no other app that is so amazingly pushed by its dev.

RN I’m using my Logitech Keyboard and Mouse happy as a dog who got a treat, with great functions and workflow upgrade! So for this, thank you!!

sorry for bothering you with this, I still couldn’t make the configuration work myself. I’m not sure what’s missing, but in case you can help, I’d appreciate it.

I’ll leave my configuration here. I added the shortcuts sepparately just to “patch” the solution for now. But it isn’t reliable enough, since “repeating” the shortcut many times over sometimes doesn’t work.
