No Insert Key (BAD Decision on Mac's Part)
On Microsoft PC computers, you'll find a very nifty little key that is labeled "Ins," which allows you to either type text into (insert) a word document OR type over (overwite) text. This is VERY HELPFUL for those who perform Word Processing tasks on regular basis, as it allows you to very easily change between inserting text (adding thought to paragraphs) or overwriting (changing thought in paragraphs), and at the same time not interrupt your thought pattern. Conversely, on a Mac computer, if you are typing in insert mode, you MUST STOP to highlight and delete the text you no longer want and then type in your added words; OR (if you've set your computer to type in overwrite mode) you MUST STOP to re-set your computer to write in insert mode. Simply put ...... either way this takes WAY MORE TIME than just simply hitting a "Ins" key that can accomplish the task quickly (as on MicroSoft PC computers). Since this disrupts one's thoughts, it proves to be a very frustrating task when needing to change back and forth between inserting and overwriting on a frequent basis.
I SUGGEST that Mac reconsider the design of the keyboard on future computers by ADDING a "Ins" (insert/overwrite) key; AND providing current users with a Short-Cut on version up-dates to enable this function on existing computers, whereby one would have to hit a combination of two keys to accomplish the task of changing between insert or overwrite.
I HOPE YOU'RE LISTENING MAC!
