MATLAB: How to use WindowKeyPressFcn while brush tool is active

brushbrushing toolguiguideMATLABwindowkeypressfcn

I have built a GUI using GUIDE which allows users to select datapoints with the brush tool, and click a push button to assign a label to the selected data. I want to also allow users to press a key on the keyboard to assign a label to the selected data, but the WindowKeyPressFcn callback only works if the brushing tool is not selected. Is there a workaround for this, or another way to take input from the keyboard while the brush is active? The goal was to speed up the process by not requiring users to move the cursor between the plot and the push buttons as much, so a solution which requires users to click somewhere else (i.e. the command line or the brush icon) before pressing a key wouldn't be very useful. Thanks!

There is a hack that can permit it. I invented one and posted it a number of years ago, but a different version was required for hg2 in R2014b and later. The adjusted version by Yair is posted at undocumentedmatlab.com
