[R-SIG-Mac] Reverse search not working in ARM binary of R-4.1.2 (or 4.1.0) from CRAN

[Simon Urbanek]

Ziv,

the released arm binaries use libedit from the system (supplied by Apple) which doesn't support reverse-search. The latest nightly binaries now include readline instead - see https://mac.R-project.org

Cheers,
Simon

I used to have ARM build of R-4.1.0 from https://cran.r-project.org/bin/macosx/ <https://cran.r-project.org/bin/macosx/>, and updated to R-4.1.2 running on my M1 Mac. Hitting ‘Ctrl+R’ (reverse search of previously run commands) did nothing on either version. It does not react in any way. Though it reacts to Ctrl+C for example, so it is respond to some signals.
