Vim Digraph
Was writing a few posts for my food blog and needed to type some some “special” characters like é. When on a Mac that’s really simple because the keymap supports typing compound keys. But I’m on Linux and switching between keyboard layouts is annoying. So I figured vim must have a way for typing these characters, and behold, I learned about Vim’s digraph support. The documentation is quite good but I’ll cherry pick some combos because otherwise I’ll forget.
The basic key combination is CTRL-K <base letter> <char>.
For example, CTRL-K u : results in ü.
| base letter | char | result |
|---|---|---|
| a/o/u | : | ä/ö/ü |
| s | s | ß |
| 1 | 2/3/4 | ½/⅓/¼ |
| a | ~ | ã |
| c | , | ç |
| = | e | € |
| c | O | © |
| + | - | ± |
| N | O | ¬ |
| M | y | µ |
| * | X | × |
| S | * | Σ |
| p | * | π |
This is super useful and I can’t believe I never knew about this.
