Description Lukas Sommer 2023-01-10 21:59:44 UTC 
SUMMARY
Key “f“ is ignored in terminal while an image is the selected tab in the document area.

STEPS TO REPRODUCE
1. Open a source code file.
2. Open the terminal.
3. Begin to type a command in the console with your keyboard. When typing the letter “f”, this letter appears in the console.
4. Open a PNG image in a new tab.
5. Click again into the terminal.
6. Try to type “f”. There will be no reaction. 

OBSERVED RESULT
While a tab with a PNG image is the currently visible tab, the letter “f” cannot be written in the terminal.

EXPECTED RESULT
The letter “f” cannot be written in the terminal, independently if a PNG image is in the current tab or not.

ADDITIONAL INFORMATION
Sometime, but not always, when typing “f”, a gray rectangle appears in the bottom right corner of the tab with the PNG image. While it is not possible to type “f” with the keyboard, it _is_ possible to copy the letter “f” from another application and to paste it into the terminal. So maybe a problem with some keyboard shortcut?

Looks similar to Bug 422203. The fix for that bug is present in KDevelop 5.7.211203.

The Part that opens PNG images intercepts keyboard events. The 'F' key toggles the "Fit image into the viewing area" option. The bug is reproducible in (almost) latest KDevelop master.

If you activate a split view (right-click on the tab bar to split views) without the PNG image, the 'F' key would be handled by the Terminal tool view, even though the PNG image would be visible in its non-active split view. I suppose another fix or a more general replacement fix is needed - one which would restrict KParts shortcuts to a widget that has focus.
