Been trying to figure this out for a while …
Z-Brush default install saves a 'Startuphotkeys.txt" file in ./Zstartup/hotkeys.
In there are a few shortcuts for direct activation of brushes, including “[BRUSH:STANDARD,5447796] // Popup+T”.
I thought “POPUP” might be
*spacebar
*right click
*“B” (for brushes)
But after invoking any of these menus, pressing “T” as well does not activate the standard brush.
Does anyone know what this “POPUP” menu is that the .txt file is referencing?
