- [ ] "./keyword" search keyword in help information
IIUC, the intended use of this is to lookup documentation for a specific language keyword, as in, e.g. ./for should open a browser window pointing to https://en.cppreference.com/w/cpp/language/for?
- [ ] ".l" for printing list of local variables (".g" does exist already for printing the list of global variables)
Not sure whether this is useful, though.

Nope, in CINT, it was acting rather as a 'search' keyword to match for predefined functions.
If I open ROOT 5.34/34, and I type ./for, I get:

Explain what you would like to see improved
Some legacy CINT commands are not available for Cling, but could be quite useful, like:
Optional: share how it could be improved
Rescue from CINT the ones considered most useful.
