There's no substitute for a mouse's ability to move the pointer around the screen in any direction and as fast as your hand can drag it. With VoiceOver enabled (Command-F5), you can use the move window keyboard shortcut. Or use the Move command first to place one side where you want it and then the Size command to resize it. You can also double-click an app’s title bar to maximize the window (as long as the option to do so is set to zoom in Dock preferences).

Since I can't remember all the shortcuts I might need, I listed them in a text file I can open in Notepad using just two easy-to-remember keyboard combinations.
I wanted to be able to use my PC without requiring a mouse or any input device other than the keyboard. There were some important shortcuts left off the list I described a couple of months ago.
