This is a completely rewritten version of the original Key Promoter
Shows the user the keyboard short-cuts when a button is pressed with the mouse. This provides an easy way to learn how to replace tedious mouse work with keyboard keys and helps to transition to a faster, mouse free development. Currently, it supports toolbar buttons, menu buttons, and tool windows and the actions therein.
The plugin was initially implemented by Dmitry Kashin and further improved by athiele. The version here is removes the custom pop-up window with IntelliJ internal message balloons. It, therefore, integrates much better into the IDE, fixes glitches and provides a more non-disruptive way of learning shortcut bindings.
