Trigger action on word selection
Answered
Hi, I am a beginner at creating plugins. I want to know how to trigger an action when a word is selected. And is it impossible to know the selected word is code or annotation. Thanks.

You can listen for changes in selection/caret position.
See `com.intellij.openapi.editor.event.EditorEventMulticaster`

I'm not sure I understand the question, but these samples might help:
https://github.com/JetBrains/intellij-community/blob/master/platform/lang-impl/src/com/intellij/internal/psiView/PsiViewerDialog.java#L1057

You can also get notifications when 'EditorSelectWord' action is executed (see ActionManager.addAnActionListener), but that won't give you events on word selection using mouse double click. For the latter, EditorEventMulticaster mentioned above might help.
