// repeat_n [how many times] [command name]
// Repeats a command the number of times specified.
// Args are "n command", where n is the number of times
// to execute the command, and command is the name of
// the command to run.
//
// Usage example: repeat_n 15 cursor_down
// This will execute the cursor-down command 15 times, with the
// expected results.

Circuitous Logic

// (1) Get and set your margin settings at desired increments.
// Assign this macro to a key combination.
// Stick your favorite margin presets into the macro code.
// I like to use 1 80 1, 1 128 1, 1 256 1, 1 512 1 and 1 1024 1.

// The same "cycling" method can be used on almost any setting.
// For example, you can easily modify this macro to take a text
// selection and cycle the text through all caps, initial caps,
// all lower case, and so on.

// Currently the macro will automatically increment to the next
// setting each time the key combo is pressed (including the
// first press). If the margins are currently 1 256 1, executing
// the command will increment the setting to 1 512 1. If 512
// is not the setting you want, just press the key combo again
// to set your desired value.
//

// (2) Cycle through display modes: hex, line hex, normal edit.
