+
+== Key map features
+
+I try to avoid C- combinations for the things I do frequently, mapping things that make sense to the <leader> key. 
+
+The leader key provides a facility for creating customized shortcuts that can be further restricted to apply only in certain modes, such as normal, insert, visual, terminal (neovim-specific), etc.
+
+The leader key is normally defined by the mapleader variable as \. 
+
