calc: Display Modes
7.7 Display Modes
=================
The commands in this section are two-key sequences beginning with the
‘d’ prefix. The ‘d l’ (‘calc-line-numbering’) and ‘d b’
(‘calc-line-breaking’) commands are described elsewhere; Stack
Basics and Normal Language Modes, respectively. Display
formats for vectors and matrices are also covered elsewhere;
Vector and Matrix Formats.
One thing all display modes have in common is their treatment of the
‘H’ prefix. This prefix causes any mode command that would normally
refresh the stack to leave the stack display alone. The word “Dirty”
will appear in the mode line when Calc thinks the stack display may not
reflect the latest mode settings.
The ‘d <RET>’ (‘calc-refresh-top’) command reformats the top stack
entry according to all the current modes. Positive prefix arguments
reformat the top N entries; negative prefix arguments reformat the
specified entry, and a prefix of zero is equivalent to ‘d <SPC>’
(‘calc-refresh’), which reformats the entire stack. For example, ‘H d s
M-2 d <RET>’ changes to scientific notation but reformats only the top
two stack entries in the new mode.
The ‘I’ prefix has another effect on the display modes. The mode is
set only temporarily; the top stack entry is reformatted according to
that mode, then the original mode setting is restored. In other words,
‘I d s’ is equivalent to ‘H d s d <RET> H d (OLD MODE)’.
