have a problem with black minimap  (or theme background color)                                                           
  after adding red marked error lines to editor and  minimap
    text is not shown in minimap (selecttion is shown, but text is not vissible)
    no text or is it behind a layer                       
    cannot find it yet

if menu buttons do not fit your screen width                                        
  use on menubar CTRL + mousescrollwheel                                
    or CTRL + - or CTRL + = to zoom in/out

NEW ! 
    menu file open from URL    
        hmmm, does not always work CORS policy 
           strange on plnkr i can load from github.io and github.com and plnkr
              on github it does not work
                should i make a php url source forwarder on my server

       maybe does beautify / prettify now (BUT NO UNDO)

You can drag move the search/replace!

???
   is the minimap / verticalscrollbar 
      in VisualStudio Monaco 
            just for decoration? ;-)

in VS Monaco 
      a search result marked selection 
         is not cleared by a mouse click on editor
   i need that 
         but please, i do not need microsoft again in this life
   
   why is there not a single working Ace demo with Emmet
???

this demo adds a vertical scrollbar
higlight search / select positions file Overview vertical scrollbar visualizer
MiniMap File OverView
links / url in the the editor highlight red underline
on mouseover and if clicked open in a new window

click on the editor text, so that the focus is on the editor
    ctrl+f search/find
    search for function
    results positions are  visible in vertical scrollbar

if you select highlight a word by doubleclck on a word
    => say doubleclick on next  => function
    it also shows occurrence positions on vertical scrollbar
    search shows more like functional
    doubleclick on function does not do functional
      changed
        added a dblclick findAll
          also changed customscrollbar code

focus must be on editor

control+, (ctrl+comma) for options
   F1 for shortcuts

ctrl+c copy
   ctrl+v paste     (mouse mid button)
   ctrl+a selectall

ctrl+f find
   ctrl+h replace

ctrl+z undo
   ctrl+y redo

ctrl+alt+mouseleft click or drag  blockselect multicursor set

focus must be on editor

only gray view is off target
    changed custom scrollbar visualizer code a bit from pixels to percent
    think it works a bit better now

other scheduler examples i do not fully understand the code
  and there are no to little comments

prefer plain javascript and not jquery,  but there is some jquery in the javascript
  wich i try to make plain javascript

try to make a scheduler from scratch with some more comments and easier to understand code

time sunrise sunset is about 7 hours of target<br>

<br>
a bar for each day<br>
click on bar should open a popup at that clicked time<br>
text field should open an analog timepicker dail that looks the same on all systems<br>
<br>
i Think most people use a phone or tablet not pc with mouse<br>
so should work for phone or tablet touch<br>
Touch drag edit popup should work<br>
