Hi @JMichaelTX,
I was able to solve this with BetterTouchTools. I don’t fully understand what Peter said, but I think something about KM not operating at a low enough level for mouse click and hold to work. Even with an until action, keeping the macro engaged, something in KM just interrupts the mouse.
In BetterTouchTools I’m using image recognition, left click and hold, and a release button.
Here are the external controllers I’m using as a trigger to auto identify the GUI control point, jump to it, click and hold it, and manipulate it.
Tactile controls over Curves in Resolve is going to be a real time saver.
Just thought I’d post in case others were struggling with click and hold. This should work on any GUI control point. I’m just using image recognition because there is no accessibility framework access to this particular GUI control point.
Here is the programming.
Thanks again for all your help.
