Overbraces and underbraces
In math mode, you can put a brace over or under an expression this way:
\startformula a + \overbrace{b + c} + \underbrace{d + e} + \doublebrace{f + g} + h \stopformula
The same goes for brackets (or other stackers):
\startformula a + \overbracket{b + c} + \underbracket{d + e} + \doublebracket{f + g} + h \stopformula
Adjusting stackers
You can adjust where the stackers start and end with the lt
(left-top), rt
(right-top), lb
(left-bottom) and rb
(right-bottom) parameters.
This feature was introduced in beta 2019-10-28.
$a + \overbrace [lt=1em] {b+c+d} + e$\blank $a + \underbrace [lt=1em] {b+c+d} + e$\blank $a + \overbrace [rb=1em] {b+c+d} + e$\blank $a + \underbrace [rb=1em] {b+c+d} + e$\blank $a + \overbrace [lt=1em,rb=1em] {b+c+d} + e$\blank $a + \underbrace [lt=1em,rb=1em] {b+c+d} + e$\blank
Interleaved braces
Some terms of an expressions can be shared by both braces, tuning the lt
, rt
, lb
and rb
parameters:
$a + \doublebrace[lt=1.4em,rt=-.3em] {b+c+d} + e$\blank $a + \doublebrace[rb=1em] {b+c+d} + e$\blank $a + \doublebrace[lt=1.4em,rt=-.3em,lb=-.3em,rb=1.5em] {b+c+d} + e$\blank $a + \doublebrace[lt=-1.6em,rb=-1.4em] {b+c+d} + e$\blank
