Many key commands are designed to incrementally adjust some aspect of the display. In general, the keyboard arrow keys and the PageUp and PageDown keys are used to increase or decrease display properties along 3 independent dimensions. To simplify embedding these adjustment commands in text strings, the printable characters 'l', 'r', 'i', 'd', '[', and ']' can be used as aliases for the arrow and Page command keys.

The meaning of the adjustment keys is controlled by the Adjustment Mode (see table below).
The magnitude of the adjustment for each key press is controlled by the current jumpsize value.

You can, however, explicitly specify the adjustment size you want by entering a number immediately before the adjustment key. For example, “10r” would be a right adjustment of size 10, regardless of the current jumpsize setting.
Note: Specifying an adjustment size of 0 means use the current jumpsize setting.

You can also specify the mode for each adjustment explicitly by entering the mode number as a second value immediately before the adjustment key. For example “10,4d” would decrease the brightness by 10, regardless of the current active mode setting.

Other punctuation special characters (e.g. ~!@#$%^&*) are used to change from one adjustment mode to another. The mode determines the meaning of the arrow keys. The default adjustment mode is Multi.
