Shortcut for upload using programmer CTRL-SHIFT-U adds "U" to source code. #2846
Description
Describe the problem
If the text cursor is in the source editing area, and I press CTRL-SHIFT-U to upload using programmer, a spurious "u" character is added to the source creating an error on any subsequent compilations (or uploads).
The same occurs if the cursor happens to be in the output area, but this doesn't affect the source code.
Other shortcut keys which use SHIFT do not appear to be affected.
To reproduce
- Open the Blink example sketch. Mine is for the Raspberry Pi Pico, but the board makes no difference.
- Click in tghe source code editor area of the IDE.
- Press CTRL-SHIFT-U to "upload using programmer".
- Check for the spurious "u" character at the cursor position.
Expected behavior
The CTRL-SHIFT-U shortcut key combination should be "eaten" before it reached the editor window.
