In the non-CodeMirror AbuseFilter editor, pressing the Tab key simply inserts a \t character (unless text is selected):
In the CodeMirror editor, however, pressing Tab on a non-empty line inserts indentation, regardless of whether any text is selected:
Sure, thanks for asking.
If we regex-search filters with the pattern \n[^\t]\t, we get quite a few matches. For example. I can find:
/* Sanitizing regular expressions (found in enwiki private filters) */ pattern := "(?x) keyword1 | keyword2 | keyword3 ...
/* Operators at the beginning (found in jawiki private filters) */ action === "edit" & user_type === 'named' ... & /* Some comment for the block */ ( user_groups contains ... )
The issue is that in CodeMirror's AbuseFilter editor, we would have to copy-and-paste existing tab characters to preserve this formatting, which may negatively impact UX.
