Holdkey

Holdkey makes it easy to type characters with accents. No more hassle with alt codes or other time consuming methods to create characters like : é à ø ü € ß ñ ï ç ö ę ğ and many many more.

Holdkey has a learning curve of about 1 minute, just type like you always do until you need a character with an accent, then hold the character for half a second, a small window with several character variations appears, then choose the one you want. Holdkey runs in the background and works with almost all programs.

Or type 2 times the accent you want to use followed by the character. For example type 2 times ' and then e gives : é or 2 times " followed u gives ü 2 times ~ followed by n gives ñ
