Insert mode mappings

[mskar]

I'd like to add the bindings like those listed in the README to my config: https://github.com/brookhong/Surfingkeys#insert-mode

How can I add the bindings below to my config?

• Ctrl-a move the cursor to the beginning of the line (default in MacOS)

  imapkey('<Ctrl-a>', '#15Move the cursor to the beginning of the line', function() {
  var element = getRealEdit();
  if (element.setSelectionRange !== undefined) {
      element.setSelectionRange(0, 0);
  } else {
      // for contenteditable div
      var selection = document.getSelection();
      selection.setPosition(selection.focusNode, 0);
      // blink cursor to bring cursor into view
      Visual.showCursor();
      Visual.hideCursor();
  }
  });

• Ctrl-b move the cursor Backward 1 character (default in MacOS)
• Ctrl-e move the cursor to the end of the line (default in MacOS and Surfingkeys)

  imapkey('<Ctrl-e>', '#15Move the cursor to the end of the line', function() {
  var element = getRealEdit();
  if (element.setSelectionRange !== undefined) {
      try {
          element.setSelectionRange(element.value.length, element.value.length);
      } catch(err) {
          if (err instanceof DOMException && err.name === "InvalidStateError") {
              // setSelectionRange does not apply
          } else {
              throw err;
          }
      }
  } else if (isEditable(element)) {
      // for contenteditable div
      if (element.childNodes.length > 0) {
          var node = element.childNodes[element.childNodes.length -1];
          if (node.nodeType === Node.TEXT_NODE) {
              document.getSelection().setPosition(node, node.data.length);
          } else {
              document.getSelection().setPosition(node, node.childNodes.length);
          }
          // blink cursor to bring cursor into view
          Visual.showCursor();
          Visual.hideCursor();
      }
  }
  });

• Ctrl-f move the cursor Forward 1 character (default in MacOS)
• Ctrl-k delete all entered characters after the cursor (default in MacOS)
• Ctrl-u delete all entered characters before the cursor (default in Surfingkeys)
• Ctrl-w delete a word backwards

  imapkey('<Ctrl-w>', '#15Delete a word backwards', function() {
  var element = getRealEdit();
  if (element.setSelectionRange !== undefined) {
      var pos = deleteNextWord(element.value, -1, element.selectionStart);
      element.value = pos[0];
      element.setSelectionRange(pos[1], pos[1]);
  } else {
      // for contenteditable div
      var selection = document.getSelection();
      var p0 = selection.focusOffset;
      document.getSelection().modify("move", "backward", "word");
      var v = selection.focusNode.data, p1 = selection.focusOffset;
      selection.focusNode.data = v.substr(0, p1) + v.substr(p0);
      selection.setPosition(selection.focusNode, p1);
  }
  });

• Ctrl-- undo
• Alt-b move the cursor Backward 1 word (default in MacOS and Surfingkeys)
• Alt-f move the cursor Forward 1 word (default in MacOS and Surfingkeys)
• Alt-d delete a word forwards (default in MacOS and Surfingkeys)

I decided to close this issue since I realized that I can rely on MacOS for most of these bindings.

I made some updates to my settings and I have had some luck with getting the mappings I want: https://raw.githubusercontent.com/mskar/setup/main/surfingkeys.js

It's important to keep settings up to date: https://github.com/brookhong/Surfingkeys/wiki/Migrate-your-settings-from-0.9.74-to-1.0
