Shortcut: CTRL + SHIFT + "letters"

[smarinr]

Hi,
im having a problem with 3 key shortcut. I'm trying to add to an action this:

action->->setShortcut(QKeySequence( (Qt::CTRL+Qt::SHIFT), Qt::Key_1))

action->->setShortcut(QKeySequence( (Qt::CTRL+Qt::SHIFT), Qt::Key_1))

To copy to clipboard, switch view to plain text mode 

but isn't trigeer, does anyone have an idea how to implement a 3 Key Shortcut??

THANKS
