With character table you can lookup any Unicode Character (except control characters) to insert into your document.

Hit alt-l to open the selection view and then find it either via unicode code point or ISO name of the character.

You can enable VIM-like digraph support. If enabled, you can hit your Mnemonic Key (default is ctrl-k) and a character mnemonic to insert a character. E.g. hit ctrl-k a : for inserting "ä".

Character Mnemonics are defined in RFC1345. They are also displayed in Character Table you get with alt-l right after the unicode codepoint.

Caveat: There is one caveat. In atom you can connect keybindings only with commands and all commands are displayed in command palette. This feature adds ~1800 commands, which makes command palette behaviour a bit slow. Need to hide these commands from it.

For minimizing added command, you can specify which mnemonics you want to use with two configuration options:

• Mnemonic Mnemonic Match
• Mnemonic Character Name Match

Enable use of character mnemonics.

Hit your Mnemonic Key (default is ctrl-k) and a character mnemonic to insert a character. E.g. hit ctrl-k a : for inserting "ä".

Mnemonic Match specifies a regular expression, which is matched against mnemonic characters.

Character Name Match specifies a regular expression with following difference:

For more readability alternatives can be separated by "," with surrounding whitespace and whitespace means any character.

If you specify latin diaresis, arrow as Character Name Match you can use latin character diaresis mnemonics and arrow character mnemonics.

Technically latin diaresis, arrow is translated into latin.*diaresis|arrow.

From Vim I am used to ctrl-k : a for inserting
