# Method 1: Mouse
# Hold Ctrl (Cmd on Mac) + click to place cursors

# Method 2: Selection
# Select a word → Ctrl+D repeatedly to select next occurrences
# Alt+F3 → Select all occurrences at once

# Method 3: Column selection
# Shift+Right-click + drag → Column selection
# Ctrl+Shift+Up/Down → Add cursor above/below

# Before — three lines to fix

# Press Ctrl+D twice to select the other two 'user_'
# Type 'customer_'
# Result:

# Split selection into lines
# Select all three lines → Ctrl+Shift+L → cursor on each line

# Adding a prefix to multiple lines
# Select the lines → Ctrl+Shift+L → Home → type prefix

# Converting CSV to array
