" Tips and Usage Notes
" ============================================================================
"
" This .vimrc provides functionality similar to your AstroNvim configuration:
"
" Key Features:
" - Leader key: Space (like AstroNvim)
" - Local leader: , (comma)
" - Buffer navigation: H/L for prev/next buffer
" - Window management: sh/sj/sk/sl for navigation
" - File operations: <leader>e for explorer
" - Clipboard integration with system
" - Modern editing features like relative numbers
"
" Main Mappings:
" - <Space>w : Save file
" - <Space>q : Quit
" - <Space>e : File explorer
" - H/L : Previous/Next buffer
" - ss/sv : Horizontal/Vertical split
" - <Esc> : Clear search highlight
" - jk/kj : Exit insert mode
"
" To extend this configuration:
" 1. Create ~/.vimrc.local for personal additions
" 2. Use :help <topic> to learn more about any setting
" 3. Install vim-plug or pathogen for plugin management
