What does tilde mean in Linux

Linux desktop à la carte - Six useful tricks

Keyboard variants - which German keyboard layout?

When installing a Linux distribution, you have to choose which German keyboard layout the Linux system should work with. There is a choice of four layouts for a German-language standard PC keyboard, each of which meets different requirements with minor differences.

Have you ever wondered why you had to type the tilden symbol (~) twice? In the normal assignment "Germany (Germany)", the accent keys with the characters ^, ~, `and‚ are not ordinary keys, but so-called "deadkeys" that accent the character of the next key pressed. For example, a “ñ” can be entered by first entering “~” and then pressing the “n”. To get the tilde, you need to press "~" twice. It is the same with the other accented characters. This is ideal for European languages, as you can also enter accented characters from Romance languages ​​despite the German layout.

If you don't need these characters, however, a simpler keyboard layout without deadkeys is better, as the characters ^ and `are more easily accessible for scripts and programming languages. To do this, select the "German (without accent keys)" layout in the settings of the desktop environment. The other two layouts "German (only acute accent marks)" and "German (only grave and acute accent marks)" are intermediate forms in which only the acute characters "or" and "are deadkeys.
