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:

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
