How to create a custom keyboard shortcut to center window in screen and resize to specific size

Question

Is there a way to create a custom keyboard shortcut that centers the current / selected window on the screen?

Is there a way to create a custom keyboard shortcut that resizes the current / selected window to a previously defined specific size?

In Windows 10, I use a small utility named "Sizer" by BrianApps (http://www.brianapps.net/sizer4/), which allows to accurately resize and reposition windows and I have grown very accustomed to it. Now, I am looking for a way to achieve this in elementary OS. Is there any additional software I could use for this same purpose?

You can get the requested functionality using wmctrl. For example, the following command moves the active window to position X:400, Y:300, and resizes it to 800x500 px.

wmctrl -r :ACTIVE: -e 0,400,300,800,500

To bind it to a key, just go to Settings > Keyboard > Shortcuts and create a custom shortcut with the command.

Check the man pages for more info about wmctrl.
