how to shortcut the increase add space after and increase space before a paragraphi

[NooZ]

I want to use two shortcuts to improve my work.

I think it is possible by scripting but i don't know how so i ask here.
 i want to create a shortcut to increase space after paraprgaph as the button in palette and one to increase the space before the paragraph.

my left mouse button and relative finger will thank you forever.

Don't bother. Below is an upgraded version of the script. It has two modes:

1. Select a text frame and all text columns are targeted.

2. Click in a text column, and only that column is targeted.

I also added something I remember I had in the script I used to have (but can't find), namely, a limit to the space to be added before the designated paragraphs. In the script you see the line

var maxAdd = 6;

which stipulates that not more than 6 points can be added to headings. Change that to any value you that meets your customer's specs.

// Select a frame to fill all columns in the frame
// Click in a text column to target just that column

(function () {

  app.scriptPreferences.measurementUnit = MeasurementUnits.POINTS;
  
  // Specify the names of the paragraph styles to target
  var headingStyles = ['SecA', 'SecB', 'SecC'];
  
  // Specify the maximum amount (in points)
  // that can be added before a style
  var maxAdd = 6;
  
  var re = new RegExp ('^(' + headingStyles.join('|') + ')$');
  var columns = [];
  var i, j;
  var frame, headings, gap, delta;

  // Return the headings in a column
  
  function findHeadings (column) {
    var a = [];
    var p = column.paragraphs.everyItem().getElements();
    for (var i = p.length-1; i >= 0; i--) {
      if (p[i] != column.paragraphs[0] 
          && re.test (p[i].appliedParagraphStyle.name)) {
        a.push (p[i]);
      }
    }
    return a;
  }

  if (app.selection.length === 0) {
    exit();
  }
  
  if (app.selection[0] instanceof TextFrame) {
    columns = app.selection[0].textColumns.everyItem().getElements();
    frame = app.selection[0];
  } else if (app.selection[0].hasOwnProperty ('baseline')) {
    columns = [app.selection[0].textColumns[0]];
    frame = app.selection[0].parentTextFrames[0];
  } else {
    exit();
  }

  for (i = 0; i < columns.length; i++) {
    
    headings = findHeadings (columns[i]);
    if (headings.length === 0) {
      continue;
    }

    gap = frame.geometricBounds[2] - columns[i].lines[-1].baseline;
    delta = gap / headings.length;
    if (delta <= maxAdd) {
      for (j = 0; j < headings.length; j++) {
        headings[j].spaceBefore += delta;
      }
    }
  }
}());

Thanks a ton, @Peter Kahrel !  When my current mayhem subsides, I will experiment with this! Very powerful.
