KeyCue 6.1

KeyCue is a very helpful application that displays a comprehensive list of all the available keyboard shortcuts on your Mac.
By pressing the command key and holding it, or by pressing it twice and holding it, depending on what settings you prefer, a table of the menu shortcuts that you can use will appear on screen.

Mac OS allows you to set up to 80 menu shortcuts for different applications or actions. KeyCue proves to be a very useful piece of software that will help you remember all of these shortcuts.

This handy utility allows you to adjust a large number of settings, such as the delay time for the table to appear on the screen and so on. Additionally, you are enabled to set the program to automatically run on system startup. You can also choose from various viewing options.
There are six themes that the table can present itself in and its transparency can be adjusted. It can prove to be inconvenient that the "Settings" window cannot be minimized (it will float over other application windows).

Briefly, KeyCue is a useful utility when keyboard shortcuts specific to the Mac OS are forgotten or not known at all, as getting used to shortcuts can improve the flow when working on a computer.
