This also applies to cable, chain, and webbing.
Gear that is anchored includes anchors, rocks, trees, tripods, trucks, etc.
A "bight" is a simple loop in a rope that does not cross itself.
A "bend" is a knot that joins two ropes together. Bends can only be attached to the end of a rope.
A "hitch" is a type of knot that must be tied around another object.
"Descending devices" (e.g., ATCs, Brake Bar Racks, Figure 8s, Rescue 8s, etc) create friction as their primary purpose. The friction in descending devices is always considered when calculating forces.
The "Safety Factor" is the ratio between the gear's breaking strength and the maximum load applied to the gear (e.g., 5:1).
You move gear by clicking and dragging it with your mouse. If multiple items are selected, all of the selected items will move.
You can move connected gear by pressing Ctrl while you move the gear (as explained below).
If you press Shift while dragging gear, the gear will move only vertically or horizontally, but not both.
You can also move gear by selecting it and then pressing the arrow keys to "nudge" it.
If you press the Shift key and then press the arrow keys, the gear moves faster.
As explained below, you can move connected gear by pressing the Ctrl key while you use the arrow keys to move the gear.
Moving gear with your keyboard is handy when you only want to move it a few pixels, when you want to move it up/down or side-to-side, and when you want to put gear near other gear but you don't want them to connect (which will happen if you drop the gear using your mouse).
If you move an item that is connected to other gear, the gear will disconnect. However, if you press and hold the Ctrl key while moving gear, the connected gear will move with the item you are dragging.
The mouse pointer will display small links 
when you hover it over gear and press Ctrl. This is a reminder that the connected gear will be moved.
The Ctrl key must be pressed before you begin moving an item or the gear will disconnect. (You can use the undo command if you accidentally disconnect an item.)
You can move connected gear when using the keyboard arrow keys by holding the Ctrl key pressed.
You can select multiple pieces of gear and then drag all of the selected gear (without pressing Ctrl).
A setting on the View toolbar controls whether an item should "snap" to the nearest gridline when it is moved.
Gear that is locked cannot be selected or moved.
Moving cable, chain, rope, and webbing is slightly different than moving other gear.
