Ergonis Software (http://www.ergonis.com) has released KeyCue 5.4, an update of the keyboard shortcut “cheat sheet.” The new version is Lion compatible.

KeyCue uses the same key symbols that are used throughout Mac OS X, but some of these are obscure and need an explanation, especially for users who are new to the Mac. Switchers will particularly appreciate the new legend, according to the folks at Ergonis. Like the shortcut table itself, the legend is compact and context-sensitive.

KeyCue 5.4 requires Mac OS X 10.4 or higher. The upgrade to KeyCue 5.4 is free for anyone who has purchased KeyCue in the last two years. For new users the cost is US$29 for a single user license.
