Questions specific to BlogAssist.
BlogAssist has a handy command in the Services menu for all apps that support it. This command takes the selected text and any text in the clipboard, and displays them in a small window similar to the floating one. When you click OK, it applies the selected operation to the text and replaces the selection in your document. Very handy.
By default this command has the keyboard shortcut of Cmd-<, (i.e. Cmd-Shift-,) but you can change it via the System Preferences. Follow these simple steps:
Note: the new keyboard shortcut won't show up in applications that are already running until after you quit and re-launch them.
If you no longer wish to use BlogAssist, or want to update it to a new version, you need to quit the application. Although BlogAssist doesn't show up in the Dock, it is still a normal Mac application. It uses a small system menu on the right-hand-side of the menubar.
The last item in this menu is the Quit BlogAssist command. Choose this, and BlogAssist will quit (optionally with a confirmation).
You can then either trash the BlogAssist application from your Applications folder, or replace it with a newer version.
If you replace it, double-clicking on the new version will add the system menu back again.

"~ ▶ Library ▶ Containers ▶ com.dejal.blogassist ▶ Data ▶ Library ▶ Preferences ▶ com.dejal.blogassist.plist".
Or as a conventional unix path:
If you are using BlogAssist Express from the Mac App Store, replace the "com.dejal.blogassist" with "com.dejal.blogassist.express" in both places, i.e.
Check out the BlogAssist User Guide; it includes lots of information about the application.
