Press the return key permanently

Ubuntu 16.04 LTS 64 bit
Audacitiy 2.1.2


for splitting a big mp3-file with vocabularies into hundreds of single word mp3-files (multiple export) I would have to press the return key too often. To avoid this I just press and hold the return key which works fine in windows but not in Linux.The numbering of the generated files seems to be too slow.

Best regards

Why is that?
If you are pressing the Return key to dismiss the Metadata editor, then there is no need to do that - just disable the Metadata editor from popping up on export:
Disable “Show Metadata Tags editor before export”
