To expand on Riamus' answer...
The following code should be placed in your remotes editor (alt+R)
menu channel {
copy window to clipboard:catch
}
alias catch {
savebuf $active caught.txt
clipboard $read(caught.txt,1)
var %i $lines(caught.txt)
var %o 1
while %o < %i {
inc %o
clipboard -an
clipboard -a $read(caught.txt,%o)
}
remove caught.txt
}
to use it, right click in the window and look for the menu(or type /catch)
