"Selection Save/Restore" as in Edit menu of old Audacity?

Windows 7 Audacity 2.3.3

Can I save and later restore a selected portion of the track’s wav form as was possible in the old Audacity by going to Edit menu’s “Selection Save” and "Selection Restore"options?

Also, is there any guide or manual specifically for the differences or changes from the old Audacity to the new Audacity? So far, every time I use the new Audacity I encounter issues such as the “selection save/restore” action stated above. Sometimes a Google search leads me to the information I’m seeking, but not always, as in this case. Search results dealt with saving a selection as…(WAV, MP3 etc.).

Many thanks to anyone helping this old dog learn new tricks!

Audacity now has a “Select” menu.
“Select menu > Region > Store / Retrieve selection”

If you use the feature frequently, you may want to create keyboard shortcuts: https://manual.audacityteam.org/man/keyboard_preferences.html

Thanks, Steve!
