如何使用VS Code将多行合并为一行？

Question

In Sublime Text 3, having multiple cursors on several lines and joining them with CMD+J results in a single line:

However, the same operation in VS Code (CTRL+J), results in half the number of initial lines (in this case 3 / 2 = 1.5 ≈ 2):

Is there a way to join all lines into one line in VS Code?

Answer 1

There is a command editor.action.joinLines which doesn't have a default keybinding. When you trigger it, you get the result you want.

{
  "key": "ctrl+alt+j",  // or your keybinding
  "command": "editor.action.joinLines"
}

No need for a cursor on the multiple lines, just select the lines you want to join and trigger the command (either with some keybinding or in the Command Palette).
