Regex templates (shortcut buttons/icons)

Useful regex can get really long and annoying to write, thus it would be cool if the extension provided small distinguishable icons/buttons for example that fill the regex field (search field) with some regex template code.

I think instead of individual icons, however, it would be easier to just show a list of text, since some regex is pretty specific and hard to translate into an icon.
