I've been trying to figure out how to invoke Siri from an external keyboard. I have one of these Zagg products: http://www.zagg.com/accessories/zaggkeys-ipad-profolio-plus-keyboard-case.php#profolioplus And my iPad supports Siri. I know that I can press a home key (on the device and keyboard) to invoke Siri for general usage. But I want to open up a text window, and then invoke Siri with my Bluetooth keyboard attached. And I also know I can turn off the BT keyboard and invoke Siri from the on screen keyboard. But I don't want to have to turn on/off the keyboard just to bring up Siri. Thanks!
