The Key Promoter X is a plugin for IntelliJ-based products like IDEA, Android Studio, or CLion, and it helps to learn essential keyboard shortcuts from mouse actions while you are working. When you use the mouse on a button inside the IDE, the Key Promoter X shows you the keyboard shortcut that you should have used instead. 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, tool windows and the actions therein.
The plugin can be installed with Settings | Plugins | Market Place and searching for Key Promoter X. When a button is clicked with the mouse, a notification pops up that shows the shortcut which can be used instead. If a button has no shortcut and is pressed several times, a notification is shown that lets you easily create a shortcut for this action.
If you click something with the mouse, the plugin will try to find out if your mouse-click invoked some IDEA action. If this is the case
and we can find a so-called
ActionID, the plugin registers this event. If your action is already connected to a shortcut, the plugin will
show you how the invoked action is called (e.g. Open Settings) and what the shortcut for the action is.
Additionally, it will save your mouse-click in the Key Promoter X statistics tool-windows so that you see which actions you are using the most and which shortcuts you should learn first.
If the action is not connected to a shortcut but has an
ActionID (which basically means we can assign a shortcut), the plugin still registers
your click. Depending on your settings under Settings | Tools | Key Promoter X, you will get a notification every x clicks on the
same action that asks you if you want to create a shortcut for this.
Be aware that there are certain mouse-clicks that, although they do something, cannot be successfully inspected and the plugin won't be able to help you with those. This for instance happens for some of the buttons in the tool-windows.
The Key Promoter X comes with built in tool-window on the right side that gives you access to your hit-list of missed shortcuts and to the the list of suppressed items.
Every mouse click that is connected to an action with a shortcut will be registered in the statistic. The items in this list are ordered by how often you missed this shortcut.
There might be some mouse actions that you don't want to replace by its shortcut. For those, you can press Don't show again in the notification and all suppressed shortcuts will appear in the list below the statistics. You can re-activate a suppressed item by double-clicking on it in the suppressed list.
The Key Promoter X toolwindow additionally allows you to clear your statistics and make a fresh start, and you can snooze the Key Promoter X notification until the restart of IDEA (or you turn it off again).
Settings for the plugin can be found under Settings | Tools | Key Promoter X.
Adjusts which buttons are allowed to show a tip. Note that the All Buttons checkbox will try to catch as many mouse-clicks as possible, even if you are not pressing a real button. This will show you for instance a tip when you hold Ctrl and press on a Java method to jump to its declaration which can be replaced by Ctrl+B.
The plugin is written in Java using IntelliJ's plugin framework. The code-base is small and contains only a handful of well documented classes, which makes it an excellent candidate to learn how to implement IntelliJ plugins.
The code is hosted on GitHub and has a Travis-CI integration for automatic building. Compilation is done with Gradle using the IntelliJ Gradle plugin and should work out of the box with a recent (v3.5) version.
If you experience bugs or weird behavior please create an issue on the bug tracker.
The initial version was implemented by Dmitry Kashin who unfortunately stopped maintaining the code and pushed the last version in 2012, more than 7 years ago.
User athiele took the time to fork the original code, fix issues and provide a version that can be used on more recent IDEA versions but stopped working on it a few years ago.
