Decide what method you will use to convert the text file. See Choosing a Conversion Method for a full discussion.
Once steps 1-3 have been completed click the Convert Button (or F5) to initiate the conversion process. Press F9 to pause the conversion process.
TIP: Once the conversion completes you can press the space bar to open the file/folder of the output files. This is because either the Edit Output File.. or the Explore Output Folder.. button becomes active once the conversion is done. So, a typical sequence of key presses would be F5 then space bar.
