`Select Group` does not use regex, even though docs say so

[chrisgrieser]

The docs mention that Select Group does use a regex, and the feature itself is labelled "Pattern". However, Select Group only accepts a literal string, things like .png$ do not seem to work.

[page-down]

I can reproduce this issue.

Click on the menu Edit -> Select Group and enter the regular expression in the dialog box. Nothing is selected. Only substrings can be matched.

Configuring key binding does not work either.

"F1" {
    id "core.select.group"
    pattern "^debug"
}
