Can I use macro on my Nexus tablet? I am enjoying my new Nexus 7 tablet PC but frustrated because I cannot use the on-screen keyboard to produce word or paragraph shortcuts. On my desktop PC I use a program called Macro Magic whereby holding down the Alt key and pressing J, for example, my email address appears. However, you can't use two keys simultaneously with a screen keyboard. I know that I could use a wireless or USB keyboard but I am unsure how to load my Macro Magic program, which is on CD, on to the Nexus. First things first; you cannot install programs written for Windows PCs, (or Macs, iPads etc.) on a tablet computer running the Android operating system. There are a few macro apps for Android but most of the one's I've tried won't work on the Nexus 7. It's a recurring problem with new devices. Android version 4.0 (codename Ice Cream Sandwich), used on the Nexus, has caught some app developers on the hop and it can take a while for updates to appear, but there is some good news. A free app from the Play Store, called CanalRun Macro Keys will work and does everything that you want. Once installed all you have to do is enable it as the default keyboard. It appears, like the standard keyboard, whenever you click on a text entry field, compose an email or start a new document, but it has an extra Fn key in the bottom left hand corner. To create shortcuts that assign a word, text string or email address to an Fn + "x" key combination, all you have to do is add a simple command line to an XML file, using another free app called ES File Explorer.
