* Use '_' key in visual mode to enter in hud mode
* Support mach0 files with multiple sections with same name
* Fix parsing of commands with nested quotes
* rename ?z to ?l
* added new command ?y to get and set yank buffer contents to stdout
* ?i stores the input into the yank buffer now
* ?I accepts a file name as argument which is loaded as hud
* ?k used as key=value temporal storage
* Add calc.c .. plans are:
  - support proper parenthesis in math.c
  - support floating point arithmetics
