How to refer to workspace variable in Matlab toolbar shortcut?

I would like to create a new toolbar shortcut that would perform some simple operation on a variable marked with a mouse in a workspace. I already have a shortcut for imagesc taken from available Matlab shortcuts. When I click on a variable and then click on the imagesc shortcut, the variable is displayed. This shortcut knows which variable to display. So my question is: what argument should I give in a script for new shortcut to pick the variable that is "clicked" in a workspace.

jDesktop     = com.mathworks.mde.desk.MLDesktop.getInstance;
jWSBrowser   = jDesktop.getClient('Workspace');
WSTable      = jWSBrowser.getComponent(0).getComponent(0).getComponent(0);
selectedRows = WSTable.getSelectedRows;

selectedVars = cell(1, numel(selectedRows));
for k = 1:numel(selectedRows)
    selectedVars{k} = WSTable.getValueAt(selectedRows(k),0);
end

Where is the variables marked? In the command window or the editor?

    activeEditor = matlab.desktop.editor.getActive;
    currentSelection = activeEditor.SelectedText;

Yair suggested this for the command window:

%# find the text area in the command window
jDesktop = com.mathworks.mde.desk.MLDesktop.getInstance;
try
  cmdWin = jDesktop.getClient('Command Window');
  jTextArea = cmdWin.getComponent(0).getViewport.getComponent(0);
catch
  commandwindow;
  jTextArea = jDesktop.getMainFrame.getFocusOwner;
end

%# read the current selection
jTxt = jTextArea.getSelectedText;

%# turn into Matlab text
currentSelection = jTxt.toCharArray'; %'

%# display
disp(currentSelection)

The variable is marked in the Workspace window. Where all current variables are shown.

Jan, thank you for your answer but do you know a method to refer to the variable "clicked" in the Workspace window (not Command Windows or Editor)?
