[GreenKeys] end of line 'thingy' on 15

[WB6BLV Central California]

The 'auto' carriage return option was fairly common on the Model 15.  Of the
four 15s here, three have that option.  Now for the weird thing... my 19 has
leaf switches on left and right front of type basket that close on space and
letters functions respectively... they appear to be factory... any idea who
or what on earth needed to count spaces or letters functions in a message?
