This item lets you replace any consecutive number of spaces with any single character. A dialog box will appear. Type the number of consecutive spaces for which Macify should wait in the first box, and the character Macify should use to replace those spaces in the second box.
Note that the character must be entered as an ASCII code number (this is so you can enter characters like Tab or Return, if you wish). If you don’t know the ASCII code, then hit the What is ASCII button for an explanation.
Also, do not forget to check the Replace as follows … box at the top of the dialog if you want Macify to actually do the search and replace as you have specified.
So, to actually convert “2 or more spaces into tabs” you would make sure the first box has a 2 in it, make sure the second box has a 9 (ASCII for Tab) in it, make sure the check box is checked, and hit the OK button.
