Ergonis Software announced the immediate availability of KeyCue 4.0 on Monday. The new version of the on-screen keyboard shortcut list added the ability to use listed keyboard shortcuts by clicking them, and also added support for the upcoming release of Mac OS X 10.5.
KeyCue displays available keyboard shortcuts for the currently active application. Version 4.0 is available for download at the Ergonis Software Web site, and is priced at €19.99 (about US$28.43). The update is free to anyone that purchased a license in the last two years.
