 +======Synopsis:​======
 +[[set]] key_interval [<​number>​]
 +
 +======Description:​======
 +This sets the timeout in milliseconds for the key input disambiguator.
 +
 +======About ambiguous keybindings:​======
 +You are permitted to create ambiguous keybindings,​ for example:
 +  /BIND ^[ PARSE_COMMAND {echo You pressed Escape!}
 +  /BIND ^%%[[%%11~ PARSE_COMMAND {echo You pressed F1!}
 +Now when you press <​escape>,​ EPIC does not know if you actually pressed
 +the <​escape>​ key, or if you pressed <f1>, and it should wait for more 
 +characters. ​ It won't know this until more characters arrive. ​ But there
 +is no guarantee that more characters will arrive. ​ This results in an 
 +ambiguous keybinding. ​ EPIC doesn'​t know which keybinding to use.
 +
 +So each time epic runs into an ambiguous keybinding, it sets a timeout
 +using this value. ​ If, at the end of the timeout, no further characters
 +have arrived, it will assume you pressed the <​escape>​ key and not the 
 +<f1> key.
 +
 +There are two conflicting issues to balance when you set this character
 +  - On a very slow telnet connection, it can take a long time for characters to make it to the remote host.  So if you set this too low, some special keys may not work correctly (like the cursor keys)
 +  - It can be annoying to have to wait a very long time after you press <​escape>​ for epic to decide that you did in fact press <​escape>​ and not something else.
 +
 +So you want to set this value to something that is big enough not to cause
 +your cursor keys and function keys to malfunction,​ but not so high as to 
 +be annoying.
 +
 +======History:​======
 +__SET__ __KEY_INTERVAL__ first appeared in EPIC4-1.1.7.
