In Dragon Naturally Speaking you may get an error message relating to next variable hotkey is in use by another application and asking you to go to Tools Options Hotkeys and change it.
This is not possible you need to add a line to the options.ini file for each user you have set up.
Here is the procedure
Dragon NaturallySpeaking is attempting to register a hot key, but a separate application has already registered that same hot key.
The Clear Variable Delimiters hot key is not configurable from the "Hot Keys" tab in the "Tools > Options" dialog. We recommend manually disabling the hot key(s) in the "options.ini" file. Each user profile will have a unique "options.ini" associated to that user.
To disable the "Select Next Variable Hot Key":
Exit from all open applications, including Dragon NaturallySpeaking 10.1.
Using Windows Explorer, browse to:
On Windows Vista: "C:\ProgramData\Nuance\NaturallySpeaking10\Users\[USER]\current"
On Windows XP: "C:\Documents and Settings\All Users\Application Data\Nuance\NaturallySpeaking10\Users\[USER]\current"
Right-click on the "options.ini" file and select "Open With", then select Notepad as the program to open the file.
Under the "[Options]" heading, enter "Select Next Variable Hot Key=0,0".
For example, the "options.ini" file should now display:
Select Next Variable Hot Key=0,0
Click "File > Save" and then close the "options.ini" file.
Launch Dragon NaturallySpeaking 10.1.
Note: Other potential hot keys that can cause conflicts may include:
Select Next Variable Hot Key
Select Previous Variable Hot Key
Transfer Text Hot Key
If the error message being displayed is referencing one of these hot keys, follow the steps above to modify the "options.ini" file, but replace the text in Step 4 with corresponding hot key. For example:
Select Next Variable Hot Key =0,0
