I wrote a GUI in which the zoom tool was frequently used, so I wanted to give it a shortcut. I wrote the figure's KeyPressFcn as follows, but it didn't work.
Q1. The "Ctrl+0" means zoom out, and it worked just fine. But "Ctrl+E" to zoom on just didn't work. How should I wrote the function `zoomKeys`?
Q2. I wanted to use "ctrl+=", but it was used by the editor to zip the codes. Can I still somehow use "Ctrl+="?
fig.KeyPressFcn = @zoomKeys;
hAxes = axes(fig);
function zoomKeys(~, event)
if strcmp(event.Modifier, 'control')
