The documentation says:
Place a single “&” in front of any character to make it the shortcut key for the button.
The & correctly gets stripped out of the display of the button, but the keyboard shortcut doesn’t work. Am I missing something? Xojo 2025r31 on macOS 15.7.3.
It fails to work on Mac 26.3 and Xojo 2025 3.1 too.
The window with the button is being called like:
reqWin=New RequestListWin
.....
reqWin.ShowModal
Have not checked on Linux but just tested on Win 10+11 using Xojo 2025 R3.1 and works as described
Sounds like macOS issue
