Increasing Temorary File Storage

I went to the link in Francis 96 reply. I had already been there and done that. The increase in storage, as Francis noted, has occurred since this summer. I have no photos on the phone. I deleted all the games and most of the apps that came with the phone.
Aside from the app from the Carrier, I've not downloaded any other apps. I have Word and Excel files. But, these are not temporary files and are accounted for in storage sense in another classification. I keep Data Sense setting on High.

So, should I assume that the Temporary Files (wouldn't it be great if I could get a list of these!) will keep expanding?

Prior to the last update the Temporary Files would decrease in real numbers, not just the rate of increase. Buying more storage as the link suggests does not make sense. Why can't the Temporary Files be deleted and I delete them?

 

Increase/decrease levels of text in PowerPoint

In Powerpoint, to increase/decrease the current line of text to the next higher/lower level I have 2 options:

1. Click to the left of the line and then press Tab / Shift-Tab

2. On the Home tab, in the Paragraph group, click the Increase/Decrease list level button

For a few months I have realized that in some documents I can do it, but in others I can only do it with option 2. Why can't I continue using option 1 (it's faster for me)?

Volume increases and decreases by itself while listening to music on Lumia 520

I purchased Noika Lumia 520 7 days ago. Whenever I listen to music the volume increases and decreases by itself and volume keys don't work at that time. I am facing this problem for last two days. Volume suddenly increases or decreases by itself. Please
suggest solutions.
