Lubuntu 20.04 Openbox keybinds windows tiling and edge snapping

Lubuntu 20.04 with LXQt do not support windows tiling and edge snapping by default. But it can be done with Openbox using keybinds shortcut.

1. Edit $HOME/.config/openbox/lxqt-rc.xml. Add below configuration between <keyboard></keyboard>.
