Firmware v10.4.0/Mac OS Sonoma regression: zoom key combo

[robbievogt]

I have had the following stanza in my $onInit for probably 6 months:

set module.keycluster.scrollSpeedDivisor 10
set module.keycluster.navigationMode.base zoomMac
set module.keycluster.navigationMode.mod zoomMac
set navigationModeAction.zoomMac.up none
set navigationModeAction.zoomMac.down none
set navigationModeAction.zoomMac.left keystroke AG-equalAndPlus
set navigationModeAction.zoomMac.right keystroke AG-minusAndUnderscore

It uses the keycluster trackball left/right for MacOS screen magnifier zoom in/out.

This has worked very well until I updated firmware today 10.1.0 --> 10.4.0.

Now it seems to be regularly dropping the modifiers, resulting in typing "-" and "=" instead of zooming in/out.

This is an extremely annoying regression, as this is functionality that I use constantly (i.e. often multiple times per minute)!

I'm on MacOS Sonoma 14.1.1.

Partial workaround: I've updated to trigger macros instead with:

set navigationModeAction.zoomMac.left macro ZoomIn
set navigationModeAction.zoomMac.right macro ZoomOut

With the ZoomIn|Out macros just defined as tap key events with appropriate combo.

This avoids the issue with typing extraneous characters, however, it's a lot less responsive and seems to be rate-limited.

Seems like this is an issue with delays or rates of events?

Interesting...

I can reproduce it. Seems like a nonzero keystrokeDelay induces it.

Do you have any other settings defined in your $onInit?

[robbievogt]

Yes, I tried a couple of different keystrokeDelay values (10, 20) and this seemed to be exacerbating the issue so I removed it again. Currently no keystrokeDelay set.

Full $onInit (with macro workaround):

set leds.fadeTimeout 5

// set keystrokeDelay 20

set module.keycluster.scrollSpeedDivisor 10
set module.keycluster.navigationMode.base zoomMac
set module.keycluster.navigationMode.mod zoomMac
set navigationModeAction.zoomMac.up none
set navigationModeAction.zoomMac.down none
// set navigationModeAction.zoomMac.left keystroke AG-equalAndPlus
// set navigationModeAction.zoomMac.right keystroke AG-minusAndUnderscore
set navigationModeAction.zoomMac.left macro ZoomIn
set navigationModeAction.zoomMac.right macro ZoomOut

set module.trackball.baseSpeed 0.7
set module.trackball.speed 0.5
set module.trackball.xceleration 1.4

set secondaryRole.defaultStrategy advanced
set secondaryRole.advanced.timeout 300
set secondaryRole.advanced.timeoutAction secondary
set secondaryRole.advanced.triggerByRelease 1
set secondaryRole.advanced.safetyMargin 20

Also, I've just now tried explicitly with set keystrokeDelay 0 and setting back to non-macro shortcut, and this seems to be working perfectly. Is there some default keystrokeDelay if it's not set explicitly?

[kareltucek]

Default is 0, but UHK does not reset its config on config saves (only on power cycles)... (Yes, this is non-intuitive and should be solved eventually.)

[kareltucek]

Well, this was introduced in 10.4.0, as part of Clear sticky modifiers when navigation mode is active..

Anyway, it should be fixed in the next release.

Sorry for the long wait and thanks for report!
