I tried searching online but I could only find names for all of the other groups of keys. Referencing this picture, all of the groups are labeled. The three keys above the group in question are actually known as "special function" keys but the area I'm interested in is shown as "other keys".
Keyboards for Mac, Android, and those for international layouts have additional keys which are generally referred to individually and do not exist in a dedicated or otherwise isolated group. Some keyboards have various alternative (usually custom) layouts which include "multimedia key" group(s) as well.
My question is, did IBM ever have a name for this group of keys with its original introduction? As they are contained in a group, I would imagine that it might have had a specific name. Maybe there is some international standard defined similar to the Model M layout which can provide an answer?
I would also be interested in any other terminology for groups of keys common to other layouts. Note that I am not interested in a comprehensive list of individual keys or specific symbol names.
A different question but on a similar tangent:
I for those who work in a text editor daily or are word processing aficionados, I have a question over at Stack Overflow on typing in the absence of these keys: How to navigate code on a keyboard with no Home/End keys and no Fn key?
For historical discussion, opinions, and personal use cases:
I've started a discussion about a noticeable absence of these keys on modern laptops and compact desktop keysboards on the VOGONS discussion forum. I would love to hear what other people have to say on the subject: http://www.vogons.org/viewtopic.php?f=5&t=60868
