Add tooltips for select by pattern dialog.
Followup to @lastonestanding's comment.
Add tooltips to the Select by Pattern dialog to:
- Explain what a diacritic is simply.
- Explain case sensitivity checkbox too.
Additionally,
- Update the tooltips to explain current behaviour, specifically how you don’t have to enter any wildcard characters for the pattern to be useful.
- Add copious notes and contexts for translators.
