Generalize the Window Command

The purpose of this draft is to examine how we might generalize the window command to handle internal tree nodes.

Selector

Format: /[RF12pblrud]+.

R
    root

F
    focused node

1
    first child

2
    second child

p
    parent

b
    brother

l,r,u,d
    left, right, up, down edge

Example

window -e right RATIO would be written window /r -r RATIO removing the need for an --edge option.

/R12bu selects the up edge of the brother node of the second child of the first child of the root.

Behaviors

Focusing

• Clear the input focus.
• Perform the border drawing instructions on all the leaves of the subtree.
• Stacking: stack each leaf?
• Behavior of focus_follows_pointer?
