Thank you, Italophile! Your suggestion led me to the following solution. I've implemented it in the main .dotm file (not necessary to put any in the secondary one). Here's the relevant code:
This is the relevant code:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui"
xmlns:nsHost="rbnManager"
xmlns:nsClient="rbnManager">
<ribbon startFromScratch="false">
<tabs>
<tab idQ="nsHost:Company" label="Company">
<group idQ="nsHost:newGroup" label="New">
<menu id="mnuMemo"
size="large"
label="Memo"
imageMso="NewPageOneNote">
<button id="btnCreateMemo"
label="New memo"
onAction="mMemo.CreateNewMemo"/>
<button id="btnEditMemo"
label="Edit memo"
onAction="mMemo.EditMemo"/>
</menu>
</group>
<group idQ="nsClient:styleManagerGroup" label="Style Manager">
<button id="btnStyleManager"
label="Paragraph Styles"
size="large"
imageMso="NewPageOneNote"
onAction="mStyleManager.ShowfrmParagraphStylesIfNecessary"/>
</group>
</tab>
</tabs>
</ribbon>
</customUI>
It would be ideal to have the xml separated (like in Italophile's post), but then I encountered that it's difficult to position the new group in the ribbon-tab. Is there a solution to the latter problem?
