Hi, @Pyxis. As @cdthomer mentioned, the wiki is a great resource. You can gain quick access to specific sections by selecting Help from the gear menu of actions.
In this case, the wiki page includes a hyperlink to the tokens %FrontWindowFrame% (== %WindowFrame%1%) and %FrontWindowPosition% (== %WindowPosition%1%). The page also includes a hyperlink to the See all Tokens page.
If you find yourself using tokens often, you might find this helpful: MACRO: Insert Token
