- KEYS AND BUTTONS
-
- This lists the use of keyboard keys and mouse buttons in Istar.
-
-
- TO DO WITH SPACING, ZOOMING, ETC.
-
- (I might have got f3/4 or f9/10 wrong way round.)
-
- # Zoom in, so boxes are smaller, so you can see more of the net: F10 key
- when mouse is placed where you want centre of KB diagram to be.
-
- # Zoom out, so boxes are larger, so you see less of the net: F9 key when
- mouse is placed where you want centre of KB diagram to be.
-
- # Move KB as a whole, up, down, left, right: Hit the cursor arrow keys
- situated between main and numeric keyboard. The amount of movement is 1
- inch by default, as set in the Prefs panel.
-
- # Create space in the net, a vertical column: F3 key, and all boxes to
- right of where mouse happens to be will be moved to right by 1 inch. All
- arrows are modified to follow the boxes as necessary.
-
- # Create space in the net, a horizontal row: F4 key, and all boxes below
- where mouse happens to be will be moved down by 1 inch. All arrows are
- modified to follow the boxes as necessary.
-
-
- TO DO WITH HIDING AND SHOWING PARTS OF NET
-
- Most of these use the numeric keypad by default.
-
- # To show all parts of net (after hiding some): 'Enter' key at bottom
- right of numeric keypad. (NOT the return key).
-
- # To show the attributes connected to the one over which mouse is resting:
- '+' (Plus) key on numeric keypad.
-
- # To show the attributes that are antecedent to the one over which the
- mouse is resting: '*' key on numeric keypad. With this you can find which
- input information is relevant to a given attribute.
-
- # To hide all, prior to showing topics: '0' key on numeric keypad.
-
- # To show the attributes or items linked to a given topic: (First hide
- all with '0' key) then hit the topic number 1..9 on numeric keypad. These
- are accumulative, in that if you hit 0 (to clear) and then 1 and 4 you will
- see those things that are linked to either topic 1 or topic 4 or both.
-
-
- TO DO THINGS TO OR WITH ITEMS OR RELATIONSHIPS
-
- # To get information click right mouse button: over box to bring up either
- attribute or item details panel, over arrow to bring up relationship
- details panel.
-
- # To perform action click left mouse button: over box to bring up
- attribute action panel. At present, items and relationships have no
- action.
-
- # To select item/attribute type to be similar to a given one: hit 'T' key
- (for 'type') when mouse is over the item or attribute box of type wanted.
-
- # To set link weight to negative or positive while drawing: hit '-' or
- '+' key on main keyboard (NOT numeric keypad) while you are in the process
- of drawing.
-
- # To bend a link while drawing it: hit space bar when end of line being
- drawn is at position for bend.
-
- # To delete a vertex (bend point) of a line: hit 'Del' key (next to
- 'help') while you are moving the vertex.
