Does vim have uppercase marks ?
Yes...though they cross files and are referred to as "file marks". You can learn more at
:help viminfo-file-marks
and at
:help :delmarks
and skim down to the section:
'a - 'z lowercase marks, valid within one file
'A - 'Z uppercase marks, also called file marks, valid between files
'0 - '9 numbered marks, set from .viminfo file
and then further down to the paragraph beginning "Uppercase marks
'A to 'Z include the file name."
