# SCRATCHPADS
# There are two commands to use any existing window as scratchpad window:
# - "move scratchpad" will move a window to the scratchpad workspace.
# This will make it invisible until you show it again.

# There is no way to open that workspace. Instead, when using scratchpad show,
# the window will be shown again, as a floating window, centered on your current
# workspace (using scratchpad show on a visible scratchpad window will make it
# hidden again, so you can have a keybinding to toggle).

# Note that this is just a normal floating window, so if you want to "remove it
# from scratchpad", you can simple make it tiling again (floating toggle).

# As the name indicates, this is useful for having a window with your favorite
# editor always at hand. However, you can also use this for other permanently
# running applications which you don’t want to see all the time: Your music
# player, alsamixer, maybe even your mail client?

#   move scratchpad

# Make the currently focused window a scratchpad
