Hello all. I'm wondering why people are having problems with the 8 Mail app. I have absolutely none and find it to be a great app and simple to use. Using the keyboard arrow keys I can scroll to any email and press Delete or Ctrl+D. I can use Ctrl+A keys to group and delete. I can scroll to an email which gets highlighted, hold down the Ctrl key, use arrow key to scroll to another, press Enter (which highlights and brings up the options menu bar), and choose an option.
Using the mouse, one can select an email by right clicking, then left click to bring up options bar, then choose an option. Hold Ctrl key and select with right or left clicking to group. This also brings up the options menu bar for options. Press the trash in upper right corner to move to Deleted folder, go to Deleted folder, select any or all, then press trash can again to delete permanantly.
This is very similar to the Live Mail program. I can perform any of this in any folder in any one of my three email accounts.
One can use the Tab key to tab through options, folders, and accounts list.

Perhaps something is wrong with the app and/or system. Please see post #10 here:

I wouldn't know about the touch navigation with any of this, for I don't have a touch screen yet.
