When using the keyboard to navigate around your environment all day every day the number of key combinations you need to remember runs into the thousands. I want a more logical system to give me access to the information I need quickly and efficiently. Layers provide that to me. If I want jaws information such as the font, window title or even currently active script I can start a layer for those commands and choose letters that seem more logical to me. then don’t have to remember if the command for title on a Braille display is t chord, control t or shift t or any combination of the three. This isn’t a negative reflection on the conventions used by companies who implement keyboard navigation, it’s simply a fact that different people find different solutions more suitable.
Layers also cut down on the number of keys that need to be pressed similtainiously allowing for one handed access when required. Take for example the wonderful Qwitter-Client for Twitter For every command in Qwitter you must hold down control, Windows key then the letter or arrow associated with that function. With layers you could specify that once in the Qwitter layer you only press single letters or arrows. This allows you to keep one hand on a Braille display for example. ith layers you can also associate Braille keys with functions that wouldn’t ordinarily be accessible from your Braille display. For example with the Focus 40 Blue you can use the wiz wheels to navigate around buffers and tweets.
With layers you could also associate different voice profiles and configuration options so that for example when in the Jaws information layer the speech rate is slower and all punction is spoken if that was required.
This idea is in it’s early stages. Please Contact me with your suggestions.
The following steps show a high level overview of the tasks required to install the Jaws Layer Commands scripts.

Make changes to your default file.

- Open the script manager by pressing JawsKey and 0. The Jaws key is the insert on a desktop keyboard or the caps lock on a laptop keyboard.

- Save the file by pressing control and s.
- Exit the script manager by pressing alt and F4.
To ensure all of the new enhancements have taken effect press control insert and escape to refresh the Jaws scripts.
The following table provides commands for starting each layer. Press the command a second time to exit that layer.

The following table gives a quick overview of the keyboard commands used by the Qwitter layer.

Jaws info commands
These don’t really provide any usability benefits. They are here as a proof of consept. The aim is to illustrate how commands could be standardised across Braille displays by using layers. Please contact me via Email if you would like any functionality added to this layer or indeed if you would like other layers to be created.
|Read window title||T chord|
|Jaws find||F chord|
Of course these commands can be written without using chords. however this functionality has not been extended to the Jaws info layer yet. Expansion of this will depend on the level of interest.
While in any buffer other scripts become temporarily unavailable. This has been done deliberitly to ensure that there can be no over lap.
My huge thanks to Sean Randall. ithout him this would be nothing mroe than idea. He’s the brains behind it.
