Hi Alan, based on your description I'd say that MoI is likely to be a good fit for you. A lot can depend on personal preferences though so I'd encourage you to download the trial version and test it out yourself some to see if it suits you or not.

A good way to get started is to read the introductory section of the help file and watch the tutorial videos which you can find here:

MoI was originally designed to work well with a pen tablet so you can do a lot of stuff with it without using right-click and without needing to touch the keyboard.
