Various old computers had their keyboards adorned with unique symbols. Companies like Commodore, Atari, Amiga, or even – in its previous life – Apple chose to put their company logos on keys, and there were other weird and obscure keys on weird and obscure keyboards.

But it was Apple’s recent push to move their American keyboards closer to European ones by embracing more iconography, that made me think of forgotten key symbols less obscure, ones that belonged to platforms we still use today. Even on a Mac and a PC, some key symbols didn’t make it to modern times. So let’s start with the PC side today since that part of the story begins earlier, and do Macs in a follow-up post.

For a lot of 20th century, a battle has been waging between words and icons. The first salvo was, perhaps, the traffic signs: America embraced words, while Europe relied more on iconography. (As much as it looks like it, it wasn’t just “graphic design vs. not”; as a more varied continent with multiple languages, Europe needed a more universal visual language to help people travelling between countries.)

This, I understand, trickled down to other things: home electronics, and computers. There, iconography also made it easier to make one product and sell it across all of Europe, without needing to introduce many SKUs with different UI strings.

Here’s IBM’s Selectric typewriter from the 1970s, in its American and European edition:

(If you’re curious, Express was a very fast Backspace, and Index moved the page down; both were prototypes of future arrow keys.)

Here’s IBM’s early 1130 computer from 1965, which sported an unusual symbol for space:

Some IBM laboratory and scientific computers in the 1970s and even 1980s veered more into iconography, but eventually lost to text as office PC users rejected the confusing symbols. As their keyboards morphed into PC/​Windows keyboards we know today, only four symbols remained and gained widespread acceptance: ⇧ for Shift, ↵ for Enter, ⇥ for Tab, and some version of an arrow for Backspace.

But let’s look at those old symbols, some beautiful, all interesting.

The two symbols below are: Print Screen (old CRT screen turning into a piece of paper) and key beep – popular when people were transitioning from loud typewriters to relatively quiet keyboards:

Here – on the front edge of the also-forgotten Reverse Tab – you can see Home, which historically meant “return to the top left corner of the screen” and sometimes even “clear the screen”:

But my favourites were these, for Insert (now gone) and Delete (still with us):

These seem inspired by proofreader marks, which feels wonderfully old-time’y:

Building on that visual language, one could also find invert/​reverse video, blinking, and underline:

And this absolute beauty, which I think meant “delete word”:

The really interesting thing is that some of those symbols survive today in Unicode. I spotted at least ⎀, ⎃, ⎁, and ⎂. The last two are for contiguous and non-contiguous underline, which I feel is a story I should know, but I don’t (yet).
