Is there in vscode a shortcut available which selects all code between matching brackets e.g. in atom this shotcut is ctrl+alt+m
I am using this extension, called Quick and Simple Text Selection - yes, that's the name :)
If you don't want to use an extension, this is the best I come up with so far: go to edit keyboard shortcuts and from there open your keybindings.json file and add the following lines
{
"key": "ctrl+'",
"command": "editor.action.smartSelect.grow",
"when": "editorTextFocus"
}
