Hotkey sequences
ALIF 2112T allows you to enter commands suitable for any KVM switch in order to choose
from up to 128 host systems. These switching commands can take the form of hotkey
sequences that emulate standard keypress combinations.
Hotkey sequences
Almost any combination of keypresses can be emulated using the following notations:
+
means press down the key that follows;
–
means release the key that follows
+–
means press and then release the key that follows
*
means add a delay. The standard delay period is 250ms, however, if a number
immediately follows the asterisk, this will define an alternate delay period (in
milliseconds)
Notes
• The entries are not case sensitive.
• All characters can be entered using their ASCII codes, from 32 to 126 (i.e. A,B,C, … 1,2,3
etc.) with the exception of the special characters above.
• It is not necessary to specify all keys to be released at the end because they are all released
automatically after the last code.
• A number of KVM switches from alternative manufacturers use hot key sequences that begin
with a press/release of either the Scroll Lock or Ctrl keys. These often require a delay between
the initial key press and the channel number to allow the switch to respond. A 500ms delay is
usually sufficient.
Examples
To send the command
Ctrl + Alt 4
you should use the following:
+Ctrl+Alt+4
.
To send the command
Ctrl + Alt 12
you should use the following:
+Ctrl+ALT+–1+2
(the ‘+–1’ entry causes the 1 key to be pressed and released before the 2 key is pressed).
To send the command
Scroll lock 1 + Enter
(with a 500ms delay) you should use the
following:
+–Scr*500+1+Ent

Creating macro sequences
Hot key macro sequences can be up to 256 characters long. All keys are assumed to be
released at the end of a line, however, you can also determine that a key is pressed and
released within a sequence. Any of the following three examples will send a command
that emulates and a press and release of the Scroll Lock key:
+SCROLL-SCROLL
+-SCROLL
+SCROLL-
Example:
+--1+ENTER
Press and release scroll twice, press 1 then enter then release all keys (equivalent
definition is +SCROLL-SCROLL-1+ENTER-1-ENTER)
Using abbreviations
To reduce the length of the key definitions, any unique abbreviation for a key can be
used. For example: “scroll”, “scr” and even “sc” all provide an identifiable match for
“ScrollLock” whereas “en” could not be used because it might mean “Enter” or “End”
(“ent” would be suitable for “Enter”).
Note: Hotkey sequences and abbreviations are not case sensitive.
