VS Code Multiple Cursors - Paste Individual Lines Repeatedly - visual-studio-code

Question

I am using VS Code with VI bindings and I am trying to do the following.
I have the following file contents:
abc="some value"
def="some other value"
ghi="some other other value"
jkl="some other other other value"
.
<etc. for many lines>
I want to make this file change to (Expected Output):
abc=${abc}
def=${def}
ghi=${ghi}
jkl=${jkl}
So far, I have first replaced =.+ with =${. I get the following:
abc=${
def=${
ghi=${
jkl=${
Then I am trying to use multiple cursors in VS Code by Cntrl + Alt + I and I am trying to copy each line from the beginning to paste it so that I get the expected output. For some reason, it isn't letting me select the whole line when I do a Cntrl + Home. Could someone please help me out with this?
For reference: The VI section of my settings.json file is as follows:
// my settings
"vim.easymotion": true,
"vim.sneak": true,
"vim.incsearch": true,
"vim.useSystemClipboard": true,
"vim.useCtrlKeys": true,
"vim.hlsearch": true,
"vim.handleKeys": {
"<C-a>": false,
"<C-f>": false,
"<C-w>" : false,
"<C-x>" : false,
"<C-c>" : false,
"<C-h>" : false,
"<C-b>" : false,
"<C-n>" : false
},

Answer 1

I don't use VI, but this is easy to do with a snippet (in your keybindings.json).
{
"key": "alt+b", // whatever keybinding you wish
"command": "editor.action.insertSnippet",
"args": {
"snippet": "${TM_SELECTED_TEXT/(.*)=.*/$1=${$1}/g}"
},
"when": "textInputFocus && editorHasSelection"
},
Then select your code and alt+b (or whatever keybinding you use). You don't need multiple cursors or need to select each line separately.

Why does it not work with Multi Cursor?
Using the default key bindings.
position cursor before a
use Ctrl+Alt+DownArrow as often as you like
use Shift+Ctrl+RightArrow select all before the =
Ctrl+C
RightArrow 2 times
Shift+End select all after the =
${
Ctrl+V
Esc
Or start selecting =" followed by
Ctrl+Shift+L LeftArrow Shift+Home Ctrl+X RightArrow Shift+End ${ Ctrl+V Home Ctrl+V Esc
