Something similar to doing

C-x 8 RET mathematical TAB TAB

but for blocks.  Where a table gets displayed and one selects 
with M-Up and M-Down, showing both the symbol and name.

A problem with 

C-x 8 RET mathematical TAB TAB

is that it only shows letters, and does not include mathematical operators.

Just categorising with "mathematical" is still too broad.

I never want NEITHER GREATER-THAN NOR EQUIVALENT TO 

And much rather select the symbol directly.  Emacs only supporting names
without showing the symbol is very annoying and time consuming.
