While creating word documents, another most laborious task is setting same kind of style like font face, font size, font color etc. for desired text block of the document (to give some more professional look to document). Some expert word users may define text style and then use that across page, but most people specifically set font setting on each selected text block. And when they have to use same text style to another text bock, then they will select that text and again set style through using font face/size dropdown and color dropdown to that block as well.
Here is the great tip for those people. You can simply use hotkey Ctrl+Shift+C to copy style of the selected text and Ctrl+Shift+V to paste copied style to selected text. It will keep your text as it is and will only applying style to the selected text block.
So next time, when you have already set font style of header of first paragraph and you want to apply same style for rest of paragraph headers, you know how to do that fast.
