# IMPORTANT:

# To make this block work, you have to edit your block-command.

|
# It should point to this file. For best performance, only use it on blocks
|
||
|
|
# which are wide and that you need to scroll.

# Example:
|

|
|
# command=~/.i3-blocks/blocks/scroll $BLOCK_NAME
|

# markup=pango

# interval=repeat
