Cheat Sheet

The Script Editor has a command cheat sheet for easy access. The model will be visible when the file code icon is selected in the editor header. Clicking on a command will copy the next to your clipboard. Paste it anywhere you like. When the parameter name is italicized, it means the parameter is optional.

Command Model

Besides the cheat sheet model, the editor can be opened in a larger popup model. This model splits the command into categories and might give a clearer picture of which command to use. The model is opened by clicking on the code icon next to the cheat sheet icon.
