[Share] Collapse fully the selected items, collection or library

[mjthoraval]

Description

The script provides a modified shortcut for the Zotero shortcuts '-' and 'Left Arrow'.

• '-': Compared to the '-' shortcut which collapses all the items or collections, this script only collapses the selected items, collection or library.
• 'Left Arrow': Compared to the 'Left Arrow' shortcut which only collapses the first level of the selected collection or library, this script collapses all the sub-levels, including collections and sub-collections. It is the same for items.

Tested with the shortcut Ctrl+R.
Similar script to expand: #562.
From the idea #357.

Note

The script gets very slow as the number selected items is large. Only use on a few items.

None

Works great, thanks!! Using Linux with Zotero 8.0.3. (For some reason, I cannot bind it to variations of the left arrow: none of Shift + Left arrow, Ctrl + Left arrow, or Alt + Left arrow work. Ctrtl + R works fine, though).
