|
|
A @scheme[hierarchical-list%] control is a list of items, some of
|
|
which can themselves be hierarchical lists. Each such sub-list has an
|
|
arrow that the user can click to hide or show the sub-list's items.
|
|
|
|
The list control supports the following default keystrokes:
|
|
|
|
@itemize{
|
|
|
|
@item{Down: move to the next entry at the current level (skipping lower levels).}
|
|
|
|
@item{Up: move to the previous entry at the current level (skipping lower levels).}
|
|
|
|
@item{Left: move to the enclosing level (only valid at embedded levels).}
|
|
|
|
@item{Right: move down in one level (only valid for lists).}
|
|
|
|
@item{Return: open/close the current selected level (only valid for lists).}
|
|
|
|
}
