Neovim Config Reference

Living reference for session management, keymaps, commands, and plugin-specific features in this config.

Session Management

Session support is automatic but user-controlled:

Manual session creation (one-time):

:mksession        # Creates Session.vim in current directory

Auto-load/save (via lua/autocmds.lua):

• On startup: auto-loads Session.vim if it exists (unless files specified on command line)
• On exit: auto-saves to Session.vim if it already exists
• Sessions are per-directory and opt-in (just create one to start using)

Stop using a session:

rm Session.vim    # Won't auto-create a new one
