Thanks Andy,
that helps a lot and showes the posibilities to extend ISE.

Next we need a way to add submenues, or menu.height becomes greater screen.heigt very soon.

And if we could get at tab_switch event, we could display the full path of the loaded files.

Of course practically I would not use block comments, because their nesting capabilities are poor.

And here the final result:

function ISE-CommentOut () {
$text = $psise.CurrentOpenedFile.editor.SelectedText
$lines = $text.Split(”`n”) |% {
$_ -replace “^”, “# ”
}
if ($lines[$lines.count -1] -eq “# “){
$lines[$lines.count -1] = “”
}
$text = [string]::join(”`n”, $lines)
$psise.CurrentOpenedFile.editor.InsertText($text)
}

function ISE-CommentIn () {
$text = $psise.CurrentOpenedFile.editor.SelectedText
$lines = $text.Split(”`n”) |% {
$_ -replace “^ *# *”, “”
}
$text = [string]::join(”`n”, $lines)
$psise.CurrentOpenedFile.editor.InsertText($text)
}

$psIse.CustomMenu.Submenus.Add(”Comment Out”, {ISE-CommentOut}, “Ctrl+K”)
$psIse.CustomMenu.Submenus.Add(”Comment In”, {ISE-CommentIn}, “Ctrl+SHift+K”)
