The "Keep Tabs" option controls how tabs are displayed on the screen
and saved to disk.

The effect of "Keep Tabs" in the editor is as follows:

With "Keep Tabs" selected all tabs are represented as actual tabs on
the display (HEX 09), that is, when you backspace over a tab, the
cursor leaps to the next tabstop to the left.

When "Keep Tabs" is not selected, a series of spaces (HEX 20) will be
placed on the display instead of an actual tab character, that is,
when you backspace over a tab it moves the cursor only one space to
the left instead of to the next tabstop.

The saved files behave in the following way:

In the saved file with "Keep Tabs" on and with leading whitespace
before the tabs/spaces, tabs will be saved as tab characters (HEX 09)
and spaces will be saved as spaces (HEX 20). With no leading
whitespace, tabs will be saved as tab characters (Hex 09) and spaces
will be saved as spaces (HEX 20).

In the saved file with "Keep Tabs" off and with leading whitespace,
the leading whitespace is converted to tabs (and spaces if necessary),
and all other whitespace is converted to spaces.
