How to select a column in Visual Studio Code on Linux

Column copied using shift + alt can be pasted as a column if you start cursor at exactly same number of lines as that of number of lines in your copied column contents.
Example:
Say the 2nd column in the following text is copied. (it has 2 rows)

foo foo1
bar bar1

Now, using same shift + alt, place cursors on two different rows. Say after 2 and 3 in below text:

1
2
3
4

Once you paste, the column will be pasted properly.

1
2foo1
3bar1
4

The trick is explained in the vscode-markdownlint repo (diff from the primary markdownlint repo):

Rules can also be configured using Code's support for user and workspace settings.

1. In Visual Studio Code, open File -> Preferences -> Settings or use CTRL + ,

2. Edit the User Settings tab on the right to something like this:

   "markdownlint.config": {
       "default": true,
       "MD007": { "indent": 4 }
   }
