Thanks,

I usually add such short javascripts to my macros by just assembling a multi-line string and then pass it to eval function; that makes it more readable than a long one-liner. Your code works fine:

//Set Foreground Color dialog:
javascript = "";
javascript += "c =Toolbar.getForegroundColor();\n";
javascript += "cNew = new ColorChooser('select foreground', c, false).getColor();\n";
javascript += "Toolbar.setForegroundColor(cNew);";
eval("script", javascript);

This also works for the background:

//Set Background Color dialog:
javascript = "";
javascript += "c =Toolbar.getBackgroundColor();\n";
javascript += "cNew = new ColorChooser('select background', c, false).getColor();\n";
javascript += "Toolbar.setBackgroundColor(cNew);";
eval("script", javascript);

Hi Stein,

here is a JavaScript example:

c=Toolbar.getForegroundColor();
cNew=new ColorChooser("select foreground", c, false).getColor();
Toolbar.setForegroundColor(cNew);

I don't know a specific macro command, but you can use 'eval' to use
JavaScript code in a macro. It's one long line; if the mailer should
split it, you have to make one line out of it:

eval('js','Toolbar.setForegroundColor(new ColorChooser("select
foreground", Toolbar.getForegroundColor(), false).getColor());');

The same should work for the background (I have not tried that).

Setting the foreground to 'red' etc:
With the recent daily builds, right-click the color picker icon and you
have a choice of the most common colors.

Nevertheless, I agree that it would be nice to have the TextField at the
bottom of the CP accepting input. It looks fairly simple - just that
someone would have to do it...
