google-app-script Pause for keyoared input/Arrowkey

Question

Just wondering if there is a way to Pause script?

function test() {
  for (var c = 1; c < 6 ; c++) {
    var d = 'A'+c;
    var value = SpreadsheetApp.getActiveSheet().getRange(d).getValue();
    var valuep = valuep + "\\n"+ value ;
    Browser.msgBox(valuep);
    *** wait for "=>" key ***
  } 
}

Answer 1

You can add Utilities.sleep(time_in_ms) to pause the execution of a Google Script.

Answer 2

Browser.msgBox automatically pauses server side script execution. As written in the official documentation ,

Note that this method causes the server-side script to be suspended.

Answer 3

To handle a pressed key event, no. Apps Script doesn't have a console to input. – @Jescanellas
