h,l keyboard shortcuts

[techtonik <techtonik@…>]

A request to add h and l to move up and down (or better say left and right) the directory tree structure expanding/collapsing leaves as needed.

There is also a bug in j,k shortcuts that they stop work after <Tab> is pressed.

Interesting idea, but there are already two assigned keys that can be used to expand/collapse a directory ('o' and 'Enter'), so I'm not sure adding 'l' would be of great help. Also, in attachment:7074-directory-expand-and-nav.2.patch:ticket:7074​ I use 'l' as a shortcut for getting to the 'l'og view.

I guess existing shortcuts were made after ​Google Experimental Search, but Google uses them to navigate plain top-down list and this is insufficient for convenient tree browsing.

Move up and down the tree actions are more sophisticated than simple expand/collapse.
Move down the tree (l key or "right"):

1. if folder is selected
   1.1 if folder is not expanded - expand it
   1.2 if the folder is expanded - move selection to the first child
2. if there is file under cursor - do nothing

Move up the tree (h key - "left"):

1. if expanded folder is selected - collapse the folder
2. if file or collapsed folder is selected - move to parent node

As for existing 'l'og shortcut - it is convenient, but may be too easy to hit 'l' when navigating sources. Can it be replaced by other key, to say 'r' for revision log?

I'll have a second look on this after committing my pending changes to the keyboard navigation.

Should probably not block 0.12.

I'll change the current 'l'og shortcut to 'L'og, so this leaves room for implementing this suggestion in a later version.
