Starts the file viewer (VIEW in TCC).
The Edit/Debug button opens the Take Command batch debugger in a new TCC tab window.
Take Command and TCC include a regular expression analyzer dialog (Ctrl-F7 from the TCC command line, or under the Tools menu in Take Command.) There are two edit boxes:
1) The first is for the regular expression to test.. If the regular expression is valid, the dialog will display a green check to the right of the expression edit box. If the regular expression is invalid, the dialog will display a red X.
2) The second edit box is for the text you want to match against the regular expression. If the text matches the regex, the dialog will display a green check to the right of the test edit box. If the text doesn't match, the dialog will display a red X.
