note: this is for your own computer as you will not be able to do the following in the Hunter lab.

One last optional alteration of jEdit for mac users.
Those who use the keyboard a bit will notice that the option key doesn’t work properly in jEdit. To get the option key working do the following:

Open the file startup.bsh in your /Applications/jEdit 4.2/startup/ folder.

Uncomment line 87 by changing the line from this:
//Debug.ALT_KEY_PRESSED_DISABLED = false;
To this:
Debug.ALT_KEY_PRESSED_DISABLED = false;

Now pressing Option + LeftArrow or Option + RightArrow will allow you to move in between words on a line quickly.
