When configuring Neovim starts to take too much effort.

Current Practice Goals ¶

• opt-; jumps to other end of the selection, like o in Neovim’s visual mode
• opt-d/c delete or change the selection without moving the deleted part to a register
• opt-. - repeat last f/F/t/T
• ctr-d/u scroll documentation windows
• spc+k open doc window for method under cursor
• gw for jumping to labels
• traversing the syntax tree
  • opt-a select all siblings
  • opt-b move to the beginning of the parent node
  • opt-up/opt-o - expand to parent node
  • opt-down/opt-i - shrink to child node
  • opt-left/opt-p - previous sibling
  • opt-right/opt-n - next sibling

Keyboard Shortcuts ¶

Navigation ¶

• opt-. repeat last f/F/t/T
• gw for jumping to labels
• ctrl-s add position to jumplist
• mm - jump to matching bracket
• n/N jump to next or previous match
• g. go to last modification

Editing ¶

• opt-d/c delete or change the selection without moving the deleted part to a register
• ~ toggle case
  • ` - lowercase, alt-` - uppercase
• "<ch>y/p - select register for yanking to or pasting from
• Q - start/stop recording
• q - repeat macro
• "<ch>q - play macro from a specific register
• C to duplicate the cursor to the next suitable line
  • opt-C for previous suitable line.

Selection ¶

• n/N add selection to next or previous match
  • toggling selection mode with v allows you to either select or to not select a given match
• opt-; jumps to other end of the selection, like o in Neovim’s visual mode
• opt-s split into selections at each line
• R - to replace selection with yanked text
• comments
  • <space>c/ctrl-c - comment
  • <space>C - block comment
  • <space>opt-c - line comment
• traversing the syntax tree
  • opt-up/opt-o - expand to parent node
  • opt-down/opt-i - shrink to child node
  • opt-left/opt-p - previous sibling
  • opt-right/opt-n - next sibling
• & - align selection
• ( and ) move between selections
• opt-, remove current selection
• opt-(/) cycles the selections backwards and forwards
  • e.g. swap the selected text to the position of the next selected text, and move the previous one to the current position¡¡
• % select the whole file
• s to select all instances of a regex pattern inside the current selection.
• opt-s to split the selection into lines.
• S split selection on matches, I think it’s like reverse of s as in everything but the regex gets matched and the regex acts as a separator between selections
• ctrl-a/x for incrementing and decrementing
  • "#ctrl-a/x for incrementing multiple selection sequentially, i.e. vim’s g ctrl-a/x

Interface and Other ¶

• ctrl-d/u scroll documentation windows
• spc+k open doc window for method under cursor
• space-? open command palette
• :sh - run shell commands
