Question
Indesign opening menus when typing
Problem:
A keyboard input (typing, arrow keys, numbers, etc.) randomly opens a keyboard shortcut menu or window for that input.
Example:
Keyboard input - down arrow
Result - File menu opens in ribbon
Fix (for Windows):
Pressing the ALT key puts you into a “shortcut mode” in which your first input will always open the menu attached to whatever key is pressed.
Turn off the “shortcut mode” by just pressing alt again.
