Three years ago I switched from Windows to Arch Linux. The one Windows feature I actually missed was PowerToys Quick Accent — hold a letter, tap space, get the accent.

The Linux alternatives didn't fit. I touch type, so anything that breaks rhythm hurts:

• Compose key — three keystrokes per character. Slow.
• Dead keys — require a keyboard layout change.
• Clipboard-based tools — overwrite the clipboard. Dead on arrival if you copy code.

So I built schnelle-umlaute — a Fcitx5 input method addon. Hold + space, get the accent. Any Unicode character is mappable. Native X11 and Wayland, no clipboard interference.

Available on the AUR, source install for other distros — setup in the README.

Feedback welcome.
