There are two scripting languages in TouchDesigner: Python and Tscript. Tscript Commands and Expression help can be found in the Commands and Expressions categories.

## Via the Textport[edit]

You can also browse commands and expressions via the textport:

**help** gives you a list of all Tscript commands and

**exhelp** gives you a list of all Expressions

Append the **-k** flag to the above commands to search for commands containing the word you are looking for. For example, to find all the expressions whose help contains the word "chop" type:

**exhelp -k chop**
