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.
