Learning shortcut keys of your favorite IDE can significantly boost your programming productivity. There is a trick to learn IntelliJ IDEA shortcuts quicker than just by memorizing them one by one.
There is a handy plugin, which helps you to learn all the necessary keyboard shortcuts in IntelliJ IDEA - Key promoter. How does it work? It is quite simple:
And that's it. The effect is two-fold. First, when you see a pop-up with the shortcut every time you click, sooner or later you remember the shortcut. Moreover, for your frequently clicked actions, the pop up becomes so annoying after a while, that you'll make anything (hopefully learn the shortcut) to avoid seeing it again. This plugin is especially useful when transitioning from a different IDE like Eclipse or NetBeans and you don't know any shortcuts at all.
What's also useful is that Key Promoter will detect that you're frequently clicking items, which currently don't have any keyboard shortcut and will offer you to create one.
Grab the plugin from the following Git repository.
Although there is a version of the plugin available in JetBrains plugin repository, it is an older original version by Dmitry Kashin, which is no longer under active development. The link provided is a fork of that original plugin by Aimo Thiele. The new version additionally provides better stats management. More important is, that starting with 2016.1 version of IDEA, the original plugin settings section is no longer accessible.
To install the plugin go to the
Settings → Plugins and select
Install Plugin from disk. Now just choose your previously downloaded file and restart the IDE.
Knowing all the useful shortcuts is no doubt handy and a big time-saver. It does, however, take some time to learn them. In the meantime, it is useful to remember some shortcuts, which can compensate for your lack of knowledge of others. The first one is Find action (Ctrl+Shift+A or ⇧⌘A) dialog, which lets you search for specific actions and commands and quickly execute them.
And of course, if everything else fails, there is always the almighty Search everywhere feature using double Shift, which also lists actions.
