(161/211) 3904 - Performance problem when using hotkeys to go to start/end of large words.

Host System:
- jEdit 5.1.0
- Java 1.7.0_65
- Ubuntu 14.04

Problem:

There seems to be a performance problem when using the special commands to go to the start (CTRL-RIGHT) or end (CTRL-LEFT) of a large word.

The editor takes some noticeable time to move the cursor from one endpoint to another, and it becomes unresponsive in the meantime.

I'm attaching a Java program that generates a file "GoToWord.txt" with a minimal toy example exposing this problem.

Thanks,
Oswaldo.
