key bindings / mode

[informatimago]

When a browser window is selected, say the package window, *esb-packages*, if we type C-h m we see that the major mode is fundamental and there is no keybinding configured to ease navigation amongst the browser windows.

Similarly, in the lisp source buffers, there's no esb minor mode providing key bindings to navigate back to the browser windows.

We could want commands to:

• switch back to the package pane

• switch back to the category pane

• switch back to the definition pane

• toggle the documentation

• navigate to the next/previous package

• navigate to the next/previous category

• select directly a category (with a prefix and f v m c or g)

• navigate to the next/previous definition

• search a package (with a DWIM name)

• search a definition (with a DWIM name)

It would be nice to have also a command to narrow to a single definition, or widen to all the forms in the source buffer.

Implemented a minor mode for selection buffers.

Use keyboard up/down arrows or C-n,C-p to move to next/previous selection.
C-f to search for selection.
Tab, Shift-Tab to switch between system browser buffers.
Press any letter to cycle through definitions starting with that letter.
