The following are keyboard shortcuts that help speed up your interactions with Jim by reducing the amount of mouse movement you have to perform.
Note: in order for any of these shortcuts to have the desired effect, the image display must have the correct input focus. For example, if the cursor is currently flashing in the place where you type in an image name, then this will receive the keyboard input, and the key-presses detailed below will not have the desired effect.
Input focus in a text field is indicated by a flashing cursor.
Click on the image with the mouse, and then your key presses will be directed at the image, and the shortcuts will work correctly.
Note: in Mac OS X Lion a new feature was introduced that disables key repeating
in Java programs. Normally, if a key is held down, the action of a key repeats, but this is not
the case in OS X Lion. To re-enable key repeating, open a terminal window, and type in the
following command (you can copy and paste it from here):
You must have either a slice selected, or all slices must have the
same zoom and pan for these shortcuts to have any effect. Press
the button to set all slices to the same
zoom and pan.
Note: these shortcuts only apply when the ROI Toolkit is active.
Then logout and log back in again, and key repeating should be enabled in Jim.
