| - | Keyboard Maestro supports calculations in almost any numeric [[/Text_Fields|text fields]]. For example you can Pause for "60*Time in Minutes". Calculations can also use comma separated lists of numbers as arrays, and can return such arrays, so you can operate on frames and points. Numeric fields often start small with up/down step arrows, but if you type anything other than a number they will expand to allow a more complex expression to be entered. You can tell that a field accepts calculations because a small BUTTON{{{C}}} shows in the field while editing it. | + | Keyboard Maestro supports calculations in almost any numeric [[/Text_Fields|text fields]].
