Description Alexander Simon 2014-10-31 13:43:37 UTC 
The method
org.netbeans.editor.BaseAction.actionPerformed(final ActionEvent evt)
register in uigestures Ctrl+Z and Ctrl+Y keys.
It is a performance issue.
Each key typing results in writing on disk about 2K unneeded info.
Fast typing person see a slowness in editor.

Compare behavior of undo/redo which is not registered.

Please filter out registration.
