// 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.

make_anchor

// make_anchor
// This nifty macro comes from John Hurst's book, Professional Slickedit,
// published by Wrox, a subsidiary of Wiley Publishing (Indianapolis),
// 2008, paperback, 472 pages. List price $49.99. The Slickedit macro code
// for make_anchor and many other macros in from Professional Slickedit
// can be downloaded freely from http://www.wrox.com/WileyCDA/WroxTitle/
// Professional-SlickEdit.productCd-0470122153,descCd-DOWNLOAD.html

// make_anchor creates an HTML anchor tag around the selected text.
// For example: if the selected text is "www.wrox.com", highlighting
// "www.wrox.com" and then executing make_anchor will produce the following:

<a href="http://www.wrox.com" www.wrox.com<a>

// This would, of course, be rendered to the user as the hyperlink
// www.wrox.com.

// Some editing software and blog editing programs
// nowadays incorporate similar functionality,
// but if you're editing plain text files in Slickedit, this macro could be
// a time saver.
