  36 ***  Support for Pick and Place files:                                   ***
  37 ***  csv-style files with/without quotes                                 ***
  38 ***  the following delimiters are supported &#039;;&#039; &#039;:&#039; &#039;|&#039; &#039;,&#039;              ***

  43 A pick and place file has 11 columns (the first two lines a file in gerbv/examplei
  44 are shown here) and looks like this:

  51 Some instructions for the first time user:
  52
  53 after loading a PNP file a new dialog will come up offering various option of
  54 selecting and graphically marking electronic parts.
  55
  56 Three modes of selecting items do exist:
  57 1)enter any search phrase and hit enter
  58      (See also paragraph &quot;SCROLLING&quot; further down)
  59         -Generally under linux regexp expressions are used such as &quot;.*&quot; i.e. &#039;*&#039;
  60         -All matches will be marked in the list AND on the screen
  61         -if you press ESC or press &lt;ENTER&gt; on an empty line it will deselect all
  62          items
  63         -if you had a selection already and you would like to add single items
  64          one by one, just hold down CTRL key while you left-click on the desired
  65          fields
  66
  67 2)just simply use left click combined with Shift and/or CTRL for manual
  68   mouse driven selections
  69   Pressing right button of mouse will not only select but also draw item on
  70   selected layer
  71
  72 3)if you have pressed &lt;ENTER&gt; on an empty phrase you first of all will deselect
  73   anything which was selected  and you can then enter the so-called &quot;assembly
  74   mode&quot; by left clicking on an item and afterwards pressing space as often as
  75   desired, while the select parts dialog is active. The selection will move
  76   down the list one by one displaying the selected part in the window
  77   automatically (with the corresponding layer being active).
  78
  79  Alternatively 1:
  80  If you had more than one item selected and you did not clear the selections list
  81  by &lt;ENTER&gt; on an empty phrase, only the first item will be taken into account
  82  and all others will be deselected.
  83
  84  Alternatively 2:
  85  You can of course also select an item by clicking on it, pressing space will
  86  then proceed as described
  87
  88  This mode also features arrows Up/Down selection, where arrow Up will reverse
  89  the action of arrow Down/Spacebar. Furthermore, holding SHIFT while pressing
  90  arrow Up/Down will increase the selection in either direction
  91 -------------------------
  92 More Features:
  93
  94 4)Inversion of selection:
  95   pressing this button at any given time inverts the selection concerning the
  96   whole list and upon clicking Mark button this new selection will be drawn
  97   onto screen.
  98
  99
 100 5)Top/bottom selection
 101   General:  press mark to mark selections on screen, after choosing to select
 102                    top or bottom parts.
 103
 104     a)in existing selection will only remove non wanted items
 105           (e.g. all bottom parts if you press &quot;top  parts&quot;) from selection
 106
 107     b)if there is no selection, all top or all bottoms parts are selected
 108
 109
 110 6)Choose available layers for marking selected parts from drop-down list
 111   HINT: if pick and place file is loaded last, already occupied layers
 112         will not be in the drop-down list
 113
 114 -------------------------------------------------------------------
 115 Hint 1:
 116 right click functionality to know Part description.
 117 After you have graphically marked a number of parts (say all resistors) you can
 118 right click onto a part which is selected in the scroll-down list of available
 119 parts in the search dialog.
 120 Its designator, comment and footprint are then shown in the statusbar and in the log window.
 121 This comes in handy if there are many parts you want to look at, but e.g. you already
 122 know a fault has occurred only on one side of the board.
 123
 124 -------------------------------------------------------------------
 125 Hint 2:
 126 SCROLLING (in the dialog window)
 127  Scrolling generally only occurs, if search for comments is not activated AND
 128  also whenever enter is hit the list will bescrolled to the first hit,
 129  regardless of the search mode.
 130  The use of BackSpace is supported.
 131  If you decide to select an entry from the list of completions offered, then the
 132  scrolling will only occur once you press enter.
 133
 134 Example:
 135  imagine you are looking for an element labelled EU3:
 136  If you hit the first key (E) to enter a search phrase in the entry field, the
 137  list will be scrolled to the first element matching this key (E), also entering
 138  a subsequent key (U) will then further refine that and scroll to the first
 139  element with EU etc.
