Keep right on waiting, until a command is added that does that
Having said that, you could script one. You need a sendkeys alias to send keystrokes to mIRC...
alias sendkeys var %a = $ticks | .comopen %a WScript.Shell | if !$comerr { .comclose %a $com(%a,SendKeys,3,bstr,$1-) }
and a command to send the keys needed to open the logview dialog...
alias viewlogs sendkeys % $+ te
Now you can use
/viewlogs
