· by Victor Mendonça · Read in about 2 min · (331 words) ·

This post will show you how to change line movement and control key bindings in macOS to be similar to what we use in Linux (and windows).

The following keyboard shortcuts will be added:

Sequence Command
Ctrl+Left Back one word
Ctrl+Right Forward one word
Ctrl+Shift+Left Back one word and modify selection
Ctrl+Shift+Right Forward one word and modify selection
Home Beginning of the line
End End of line
Shift+Home Beginning of the line and modify selection
Shift+End End of line and modify selection
Ctrl+Home Top of page
Ctrl+End End of page
Shift+Ctrl+Home Top of page and modify selection
Shift+Ctrl+End End of page and modify selection

Instructions

a. First create the folder ~/Library/KeyBindings/ and then the file DefaultKeyBinding.Dict

mkdir ~/Library/KeyBindings/
vim DefaultKeyBinding.Dict

b. Add the contents below to the new file:

{
    /* Ctrl + Left */
    /* "^\UF702"  = "moveWordLeft:"; */
    "@\UF702"  = "moveWordLeft:";

    /* Ctrl + Right */
    /* "^\UF703"  = "moveWordRight:"; */
    "@\UF703"  = "moveWordRight:";

    /* Ctrl + Shift + Left */
    /* "^$\UF702" = "moveWordLeftAndModifySelection:";*/
    "@$\UF702" = "moveWordLeftAndModifySelection:";

    /* Ctrl + Shift + Right */
    /* "^$\UF703" = "moveWordRightAndModifySelection:";*/
    "@$\UF703" = "moveWordRightAndModifySelection:";

    /* Remap Home / End keys */
    /* Home Button*/
    "\UF729" = "moveToBeginningOfLine:";
    /* End Button */
    "\UF72B" = "moveToEndOfLine:";

    /* Shift + Home Button */
    "$\UF729" = "moveToBeginningOfLineAndModifySelection:";

    /* Shift + End Button */
    "$\UF72B" = "moveToEndOfLineAndModifySelection:";

    /* Ctrl + Home Button */
    /* "^\UF729" = "moveToBeginningOfDocument:"; */
    "@\UF729" = "moveToBeginningOfDocument:";

    /* Ctrl + End Button */
    /* "^\UF72B" = "moveToEndOfDocument:"; */
    "@\UF72B" = "moveToEndOfDocument:";

    /* Shift + Ctrl + Home Button */
    /* "$^\UF729" = "moveToBeginningOfDocumentAndModifySelection:"; */
    "$@\UF729" = "moveToBeginningOfDocumentAndModifySelection:";

    /* Shift + Ctrl + End Button*/
    /* "$^\UF72B" = "moveToEndOfDocumentAndModifySelection:"; */
    "$@\UF72B" = "moveToEndOfDocumentAndModifySelection:";
}

Note: The code above assumes you are have substituted the Command Key for the Control Key in «Keyboard => Modifier Keys…» (see screenshot below). If you haven’t, you can try changing the comment between the commented and uncommented blocks.

c. Restart the application you want to use
