s, a descriptor for a documentation node (see below for examples)
Consequences:
The given documentation page is displayed using info, if you are running Macaulay2 in a terminal window.
Description
Some example uses:
infoHelp "Macaulay 2" -- top of Macaulay2 doc
infoHelp ideal -- online doc for the 'ideal' function
infoHelp "matrices" -- overview of matrices in Macaulay 2
infoHelp (ideal,List) -- online doc for ideal(List) method
infoHelp (diff,Matrix,Matrix) -- online doc for the diff function taking two matrices as arguments
infoHelp [gb,DegreeLimit] -- view doc for the optional argument DegreeLimit to gb function
infoHelp (symbol**,Matrix,Matrix) -- view doc for Matrix**Matrix
While in the info program, there are many ways to navigate and search. Besides the arrow keys to move around on the page, here is a list of the most useful key strokes:
? -- display information about all of the possible keystrokes
q -- quit info, return to Macaulay2
n -- go to the next documentation node
p -- go to the revious node
m -- follow the menu link
r -- follow a cross-reference
l -- go to the last node visited
Caveat
The help command allows other possible arguments, such as help methods ideal, but infoHelp requires that the argument s refers to only one documentation page.
