The extensions of this method
Each extension, and whether it exists for this method; an extension that exists combines with the others (FindSTCS).
Extension
Exists
What it adds · The names
Q
yes
does what the method does, then returns the object, so the call can be chained · RemoveAllCSQ
QQ
no
chains on the next, more specific type of object (the Q ladder)
QQQ
no
chains on the most specific type of object (the Q ladder)
QRT
no
returns the result as an object of the requested type
CS
yes
takes a case-sensitivity flag · RemoveAllCS, RemoveAllCSQ
ST
no
takes the position to start from (StartingAt)
IB
no
takes bounds that are included (IncludingBounds)
XT
no
the extended form: more parameters than the base method
XTT
no
yet another extension: a further extended form, after XT
Z
no
includes the position in what it returns
ZZ
no
returns positions as sections, [start, end]
W
no
selects by a condition
WF
no
selects by a condition, with the expressive keywords (@NextItem, @PreviousItem...)
D
no
takes a direction, forward or backward (Directional)
F
no
takes a function (the condition or the update is given as a function); the forms document also uses F for the future form, which defers the action
Many
no
works on a collection of items instead of one (the plural form)
Except
yes
takes exceptions, what to leave out (the exceptional form) · RemoveAllExcept
U
no
returns the result without duplication
