KeyBindings

• move around like in any vim buffer
• <CR> on .. will cd in the above directory
• . will cd in the directory under the cursor
• type a to add a file
• type r to rename a file
• type d to delete a file (will prompt for confirmation)
• if the file is a directory, <CR> will open the directory
• otherwise it will open the file in the buffer near the tree
• if the file is a symlink, <CR> will follow the symlink
• type <C-v> will open the file in a vertical split
• type <C-x> will open the file in a horizontal split
• type <C-t> will open the file in a new tab
• Double left click acts like <CR>
• Double right click acts like .

Features

• Open file in current buffer or in split with FzF like bindings (<CR>, <C-v>, <C-x>, <C-t>)
• File icons with vim-devicons
• Syntax highlighting (exa like)
• Change directory with .
• Add / Rename / delete files

TODO

• Tree creation could be async
• bufferize tree
• better default colors (use vim highlight groups)
