LibreOffice has a pretty limited method of assigning the key to accept autocorrections, I know what three of the five options are, but have no idea what the other two options represent.
To get to the keymappings in question, follow this process:
LibreOffice Writer
"Tools" menu
"AutoCorrect Options..." submenu option
"Word Completion" tab
"Accept With" drop-down options:
↘ - ? ________ ?
↩ - enter/return
‿ - space bar
➞ - ? ________ ?
⇥ - tab
What keys do the southeast arrow () and the rightwards arrow (➞) represent?
