Windows SDL, GDI
If you used Ctrl+V when input isn't focused, simutrans recognize each character as commad.
Ctrl+V should be ignored when text input isn't focused.

[EDIT]
For example.
1. Start simutrans with pak128.
2. Copy text below to clipboard

Stesttest
Ltesttest
cX

3. Activate simutrans window.
4. Press Ctrl+V

Result:
1. Save game as testtest.sve.
2. Load testtest.sve.
3. Take a screenshot
4. Quit simutrans.

Reminds me of vi: Put your name in vi and watch what happens Of course you are right

[VS]

Keep it under another shortcut as macros!
