How to press a key using an alias
From Scriptwiki
With this alias, you are able to "send keys" to the active window, this doesnt have to be mIRC. For descriptions of all the keys, see: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/script56/html/wsmthsendkeys.asp
alias sendkey { set -l %name sendkeys $+ $ticks .comopen %name WScript.Shell .comclose %name $com(%name,SendKeys,3,bstr,$1-) }
Example
/sendkey {F1}
This sends the F1-Key to the active window.
