Built-in variable for TAB character?

Hi All,

When reviewing 2.6.4 Built-in variables I noticed there was no built-in variable for the TAB character only SPACE mentioned in the documentation.

As RF uses both space and tab characters as delimiters shouldn’t tab also have a built-in variable?
Is there already a built-in variable for tab ${TAB} or ${\t} that just got missed from the documentation?

This is not causing me any issues and I could workaround it with a regex keyword if I needed to, so this is a question of curiosity.

NB: If there was a category for documentation I would have put this there, this was the next best place
