Guys,
If you want an easy right click I discovered using otg adapter by Jolouis with mouse you get instant right click on any menu.The mouse works on all apps I've tried so far on KDE. Also the cjk keyboard for foreign text is the best keyboard I have used on KDE thus far. Does numbers and text easily. If someone can how me how to do a screen shot in KDE I will take some screen shots to show right and keyboard. Hope this helps. Dan
