in Eclipse i used for years a phpstorm Shortcut Trainer.
It works like this:
if i used mouse click. it only shows me the shortcut. all mouse click was ignored.
very good for training.
i search also the posibility to get the hint text faster (200 miliseconds).
please note in every hint shortcut information.
The goal of the MouseFeed plugin is to make Eclipse users faster. This approach is complementary to the efforts targeting higher-level productivity. See the MouseFeed project blog for more information.
Operating UI with keyboard is much faster than with a mouse. MouseFeed helps to form a habit of using keyboard shortcuts. When the user clicks on a button or on a menu item, the plugin shows a popup reminding about the key shortcut.
This is how it works - click on the Search toolbar button and you'll see a popup with the keyboard shortcut reminder:
You can specify a per-action configuration, you can also configure MouseFeed to completely prevent actions from running unless they are called by a keyboard shortcut.
