Headers

Headers appear in an emphasized font style in both panels of the editor, thus they can be used to visually distinguish them from the rest of the document and organize content into a single paragraph.

Headers can be created by placing the '#' character at the beginning of a line.

# Banking Costs
Bank of America = $50 000/year + 5.25%
Citibank = $50 000/year + 6%
the difference in 3 years is (Citibank - Bank of America) * 3years
# Math lesson
a  =  -9.8m/s^2
v0 = 100  m/s
x0 = 490  m
t  =   1  s
x = 1/2*a*t^2 + v0*t + x0

The line of a header is not evaluated; calculations cannot be performed within it.

The /sum attribute can be placed in the header, which changes its value and displays the total value of the lines found beneath the header.

#Budget /sum
food $500
mortgage $2000
bills $1500

As can be seen, in this case, the text found in the header does not appear at all (this is to ensure that the summarized value aligns nicely with the results below it, enhancing readability).
This can currently be compensated for by writing an additional header above it with the desired title text, e.g.

#Budget
#Budget /sum
food $500
mortgage $2000
bills $1500

Comments

Every text that follows the // characters will be commented out, their content will not be evaluated.
Additionally, individual items can be excluded from the expression by placing a ' character in front of them.

v0 = 100  m/s
x0 = 490  m
t  =   1  s
x = 1/2*a*t^2 + // v0*t + x0
v1 = 150  m/s
// Notice that below, v0 is ignored
x = 1/2*a*t^2 +'v0 v1*t + x0
