Hi, Thanks for the issue report. Goneovim does not allow M-mapping by default in Mac OS. (Note that the Alt key prefix is A- in Goneovim.) To use it, you must set Macmeta to true in settings.toml. In a launched instance, the settings can be controlled with GuiMacmeta [0|1].

I have looked into a few past cases, and it seems that controlling at the MacOS configuration level is also effective.
