Shortcuts for MOUNT, CHDIR and DIR U12,P

[sir-lazarus]

Shortcut for MOUNT command:
Similar to the ones for loading (/) and starting (^)?
So that I can write e.g. # at start of a line within a directory list of the SD-Card to mount that D81/D64-File-Entry to the default unit.

Shortcut for CHDIR command:
Same with a shortcut e.g. § for the CHDIR command to change the current directory of the SD-Card to directory of the entry (without adding the part for ",U12" manually because it will be then assumed automatically).

Shortcut e.g. $$ for DIR U12,P to list the directory of the SD-Card paginated
