set(handles.popupmenu, 'Value', 1)
where popupmenu is replaced by the tag of the pop up menu.

Use addlistener to listen to 'PostSet' events of the string changing in other uicontrols.
function showStringUpdate
%Figure
hFig = figure;
%Listbox
hList = uicontrol('Style','listbox',...
'Units','normalized',...
'Position',[0.5 0.1 0.3 0.5],...
'String',{'Hello World','It''s Friday','And a Three day Weekend!'},...
'Max',1,... %Increase for multiselect
'Value',1,...
'Callback',[]);
%Editboxes
for ii = 3:-1:1
h(ii) = uicontrol('Style','edit',...
'Units','normalized',...
'Position',[0.1 0.1*ii 0.3 0.1],...
'String','Type in Me',...
'Callback',[]);
addlistener(h(ii),'String','PostSet',@(src,evt)set(hList,'Value',1));
end
end
Save this, move the listbox selection to something else, and then type in any box.
