Custom key mappings¶

There are many custom keymappings in this config. The majority is defined in plugins/command_center.lua forming a command palette which can be activated by A-p. This is similar to the command palette known in other editors. It shows keymappings and command descriptions, is divided into categories and searchable like any other Telescope picker.

Some essential commands are defined in keymap.lua, particularly those that should always be available even when the command palette is not (yet) loaded.

Alt-Cursorkey is used to navigate windows, so A-Left goes to the left window, A-Down to the split below the current and so on.

Key notation is in the Vim format without angle brackets. So leader n means to hit the leader key followed by n, C-n means Ctrl-n and so on.

Some keymaps use the notation of a root directory. This is defined as the project root directory for the active buffer. To find it, various utility functions are used for a best guess approach. If the file is under GIT version control, then the GIT root will be used. If it is not, a pattern approach similar to LSP config will be used to find typical project root patterns. Note that this might fail and return nil in which case the directory of the active buffer will be used.

File pickers (Telescope)¶

key	modes	meaning
C-p	n	Select recent file (Telescope oldfiles)
C-e	n,i	Select buffer (loaded or unloaded, Telescope buffers)
F8	n	Find files in the `root` directory of the active buffer

Keys related to Nvim-Tree or Neotree¶

key	modes	meaning
leader ,	n	Toggle the tree on the left side
leader r	n	Find the current file in the tree
leader R	n	Sync the tree with the project root directory of the current file
leader nr	n	sync tree with the parent folder of the current file

keys related to the terminal frame¶

The terminal split is always opened below the current one. This works as toggle, if it’s open, it will be closed. See the docs of how to avoid opening a terminal on startup.

key	modes	meaning
F11	n	Toggle the terminal frame at the bottom

Navigating the main areas (aka split)¶

The main window is basically divided into four areas. The file tree on the left side, the main editor window in the center, a terminal split right below it and an optional outline view on the right side of the main editor area. There are quick navigation keys to focus these frames as follows:

key	modes	meaning
A-1	n,i,t,v	Focus the left frame (file tree)
A-2	n,i,t,v	Focus the main text area
A-3	n,i,t,v	Open or Focus the symbol outline tree (when available)
A-4	n,i,t,v	Open or focus the terminal

Note that this also works when the editor was started in plain mode without an active file tree and terminal split.

Various navigation helpers¶

key	modes	meaning
A-Backspace	n,i	Activate the jumplist (recent edit locations)
A-S-Left	n,i	Go back to previous edit location (like C-o)
A-S-Right	n,i	Go to next edit location (like C-i)

Quickfix mapping¶

key	modes	meaning
A-S-Down	n,i	Next quickfix location
A-S-Up	n,i	Previous quickfix location
C-f c	n,i	Close quickfix split

Various keys¶

key	modes	meaning
F1	i	LSP Symbol hover information
S-F1	i	LSP parameter (signature) help
F4	n,i	Save a view of the current file (persistent folds)
F5	n,i	clear search highlights (also those from hlslens

Format paragraph¶

key	modes	meaning
A-C-w	i,n	Format paragraph to current text width. Use soft line breaks

CMP (completion) mapping.¶

These mappings are defined in lua/plugins/cmp.lua which contains all cmp-related configuration. Standard keybindings are used to activate manual completion (C-Space) and select completion suggestions (Tab).
