How to select all instances of a variable and edit variable name in Sublime

Question

If I select a variable (not just any string) in my code, all other instances of that variable get a stroke (white outline) around them:

Is there a keyboard shortcut that will let me select all of those instances of the variable and edit them all at once?

Things I've Tried:

⌘D, ⌘K, and ⌘U lets me select them one-by-one, but I have to manually exclude the non-variable string matches:

And using Ctrl⌘G simply selects all the string matches:

Clearly, Sublime is able to differentiate between variable and string matches. Is there no way to select just the variable matches?

Answer 1

1. Put the cursor in the variable.

   Note: the key is to start with an empty selection. Don't highlight; just put your cursor there.

2. Press ⌘D as needed. Not on a Mac? Use CtrlD.

Didn't work? Try again, making sure to start with nothing selected.

More commands:

Find All: Ctrl⌘G selects all occurences at once. Not on a Mac? AltF3

Undo Selection: ⌘U steps backwards. Not on a Mac? CtrlU

Quick Skip Next: ⌘K⌘D skips the next occurence. Not on a Mac? CtrlKCtrlD

Answer 2

I know the question is about Macs, but I got here searching the answer for Ubuntu, so I guess my answer could be useful to someone.

Easy way to do it: AltF3.
