Screen readers are indispensable tools for the computer user or IT professional who is visually impaired or blind. SecureCRT is compatible with a variety of screen readers, such as Freedom Scientific's JAWS, and you can optimize your screen reader's behavior with SecureCRT using scripts.
This tip discusses the JAWS scripting capability, and provides sample JAWS scripts that can help you make the most of your SecureCRT work environment.
Without scripts, JAWS automatically speaks the SecureCRT menus and controls when you use them. In order for JAWS to speak the text inside the emulation window, the JAWS echo text setting must be set to "ALL", which causes JAWS to speak all text that has changed or is new on your computer screen. This can be distracting since you hear content that might be extraneous, such as the announcement of the clock change every minute.
To customize how the terminal emulation window text is spoken, Harald van Breederode, a SecureCRT customer from The Netherlands, wrote a group of scripts that let you be more selective about what information the screen reader speaks and ignores.
The main function in the scripts is the NewTextEvent function, which is called by JAWS whenever the content of the computer screen changes and determines what is spoken. The NewTextEvent function re-sends all screen text when the screen contents get refreshed, for example, when you switch sessions or when you ALT+TAB back into SecureCRT.
By default, the example scripts tell JAWS to speak new text that appears in the emulation window. This echoing can be toggled by pressing the JAWSKey+X. The script announces itself whenever SecureCRT is launched and announces the session title whenever you switch sessions with CTRL+TAB and when you ALT+TAB into SecureCRT. Pressing JAWSKey+H gives an overview of the hotkeys used within the scripts. If you need to re-read screen contents, you can walk with the JAWS cursor and the screen will scroll up and down as needed.
Below you'll find a link to a WinZip file containing the JAWS script files for use with SecureCRT. After downloading the zip file, extract the scripts to your JAWS \settings\enu directory. If you are not familiar with JAWS scripting, you should first review the JAWS Basics of Scripting Manual.
