Delete an entire word Instead of deleting a single letter, pressing CTRL + BKSP will delete the entire word behind the cursor. This makes deleting text quicker if you screw up a whole word.
Move Cursor to beginning of the next or previous word Moving the cursor around manually while typing is a great way to make your work take longer than it needs to. To speed of the process, move the cursor around with keyboard shortcuts. To move it to the beginning of the previous word, use CTRL + Left Arrow. To move it to the beginning of the next word, use CTRL + Right Arrow. In OS X you can accomplish the same using the Option key.
Making sub and superscript text If you need to make sub or superscript text (think exponents for superscript), press CTRL + = for subscript and CTRL + SHIFT + = for superscript.
Paste plain text of what was copied When you copy text from any source, programs will usually copy any formatting that comes with it. To paste this as plain text, press CTRL + Shift + V instead of the standard CTRL + V, and the system will paste unformatted text.
Note that many programs follow this parameter (Chrome, Firefox, etc.) but not all, particularly Microsoft programs like Word or Outlook. For those there’s a few alternatives that go beyond copying and pasting in Notepad: 1) CTRL + ALT + V will show a ‘paste special’ dialog box. 2) CTRL + Spacebar will remove formatting in already pasted text. 3) Download Puretext and choose a hotkey to always paste plain text with it.
