- If you can't find something promising within a 10-30 minutes then ask for help.
- Don't bang your head against the wall when creating macros either.
- If you fail to make progress for 20 minutes to an hour it's time to holler uncle and ask for help.
On the other hand – people who are new to Keyboard Maestro have a lot to learn and many want to run before they can walk.
- Look at and experiment with KM's default macros.
- Search the forum and play with macros you find interesting.
- Remember to use the search field in the help menu of the Keyboard Maestro Editor.
- Examine the menus of the editor carefully, so you get a feel for what's there.
- Especially the insert items in the Edit menu (note the keyboard shortcuts).
- Look at the sort and select options in the View menu.
- Hold down the Option key when perusing the Edit menu to see help links to the Keyboard Maestro wiki.
- Be aware of the Wiki as a resource.
