There are many, many keyboard shortcuts which are much faster than swapping back and forth to a mouse.
Just one, however, has saved me lots of grief and wasted time. Let's not forget the magic 'Ctrl Z'! Although a fairly standard Windows(?) keyboard shortcut (along with the rest of the generic shortcuts mentioned in the article) this is the one that will restore just about anything you've stuffed, either accidentally or deliberately (and then changed your mind a microsecond after hitting the 'Delete' key).
Can't say I agree about the efficiency of your method of moving text around. Simply highlight the text and use the mouse to left click, hold and drag. Let go of the mouse button and the highlighted text moves to the right of the cursor.
Both your and my tips are OK if you're moving text on the same page, but it's hard to beat the old Ctrl-X (cut) then move to wherever you need to put this bit of info and Ctrl-V (paste) to put the text after the cursor position. This method is near universal - anywhere within a document, into a new document, and for just about any type of document. It is far easier to learn and use one universal shortcut, IMHO, than ones that may be specific to just one program, etc.
A lot of the generic shortcuts are also time savers, like shift+end to highlight to the end of the line,
Ctrl+Rt Arrow to shift along the line in words not individual letters, etc.
Anyone who has grown up with DOS word processors will find a lot of keyboard shortcuts go back to those days. Trouble is, this means you will be at an age where remembering them is ... um ... difficult.
It is often said of modern word processors that 90% of people use just 10% of the inbuilt features. I've been using Libre Office (and its parents, Open Office and Star Office) since the beginning, and I am still finding features (and quick ways of accessing them) I never knew existed (probably because I've not needed them previously).
