While there are a great number of useful windows 10 shortcuts, I have the list below the combination, which I use daily.  Many of the shortcuts can be used across multiple applications (e.g. Notepad++, MS Word, SQL Server, Dbeaver, etc.) and save a considerable amount of mouse work.  Overall, these shortcut keys are more efficient and faster than using the mouse to perform the same task on a repetitive basis.

You may want to investigate the numerous other Windows 10 shortcuts keys, which best apply to your daily activities, but these are the ones, which I have found most useful and which I have committed to memory.
