Hi Joseph,
You are probably right that this should be a separate thread. However, I just want to point out that your whole explanation about JawsScripps etc. is he relevant to the average user who does not really care about programming, scripting, etc. The average user wants to use the screen reader and is not interested in all the stuff that you talked about in your last message. So when you design an interface, you need to have the average user in mind. That is the person who wants to do a task with the computer, not the geek, not the techie, and not the programmer.  Do you honestly think that the hundreds of millions of computer users throughout the world, that is the cited users, would be using computers if they had to deal with this crap? The answer is no. That’s why they invented the graphic user interface. It’s easy for sighted people. What blind programmers and others who want to make screen readers need to do is make the screen reader interface as friendly as possible for the average non-techie person.
and that means using plain language where ever possible, even if it isn’t nice and elegant.g

I think we should devote a separate thread for it, but to give you a short answer:

Those of you coming from JAWS scripting world might be familiar with the terms “script” and “function”. They are essentially the same: both perform something which can be called upon from other places. The crucial difference is how it is invoked: a script is a function with a piece of input attached.

In the same way, NVDA code can define functions (they are really Python functions). Just like JAWS scripts, the one difference between a function and a script is how you invoke it: you need a piece of input to invoke a script (basically a specially tagged function), which can call other functions, run other scripts, and even kill NVDA (if you want, but don’t try that at home). As long as any kind of command is assigned to a script (keyboard command, a touchscreen gesture, a braille display hardware button, etc.), NVDA will let you perform something. This is why you can assign touch commands to keyboard commands and vice versa, because NVDA do let you assign (technically called “binding”) all sorts of input mechanism for a command (for instance, just as you can use keyboard to perform object navigation routines, a set of touch swipes has been defined to perform object navigation; in fact, these commands call the same routine).

Good idea. There is probably some programming thing that gets in the way. I hope not though, because it makes very much sense.

Why couldn't they be in different preference categories? Braille for Braille, Keyboard for Keyboard, Gestures for Touch screens and Voice control for Voice control?

The problem is, what should this array of ways of input be called?  Maybe input commands, which would cover everything.  This is just one more example of the decline of English.  Apps and applications, two different things, are used increasingly interchangeably.  the language in general is becoming less precise and accurate and this is just one area.

Input gestures are more abstract

Which is precisely the problem.  Callin something that is intimately familiar to the typical end user, and when it's currently the only method (regardless of keyboard being used), something "more abstract" is not the way to go. 

The folks at NV Access are far from the only software developers to go this route.   Almost every time it's the route taken it makes things more opaque to the target demographic, which is why it should be avoided in the first place.
