[car] @sri429 This may seem off the wall, and I know you said "i dont want to give a random shortcut"... but years ago in Eclipse we decided to use the F2 key to open "more info" in our code editor. Stuff like comments, annotations (bookmark/breakpoint/error/warning), etc. In short, any popup info that a mouse user could get on hover at a specific location was also accessible via keyboard F2 at the caret location. These "tooltips" could also contain interactive controls, such as a "Quick Fix" button for a syntax error, etc.
https://shortcutworld.com/en/Eclipse/win/all (and find F2 on this page).
Anyhow, F2 is often used for "Rename", so if your li's can be renamed, then this would not be helpful.
F2 has also been used for "more stuff to do/see for the focused thing" (MS Excel - edit current cell), so this is perhaps not completely crazy... ;)
