Hi peter, to set up the script first go to the Options dialog, the button for it is on the bottom toolbar right-hand side. The left-hand side of the Options dialog has different categories listed, click on the "Shortcut keys" label. Now you're in the list of shortcut keys and you can click the "Add" button to add in a new shortcut key at the top of the list.

A shortcut key is made up of 2 text fields, a "Key" field on the left column and a "Command" field on the right column. You put whatever keyboard key you want to use in the "Key" column, for example if you want this snap script to run when you push the S key then just type in S for the Key part.

Then for the Command part that's where you should paste in the script from above, highlight the chunk of text that starts with script: in your web browser, copy that then click in the Command field for your new shortcut key and paste.
