XYplorer Beta Club

Hello,
I have a couple of questions with respect to tabs. In XYplorer, I have a vertical folder pane to the left and two horisontal list panes to the right. Both the upper and the lower list pane has a lot of tabs, and quite a few of them are out of view (that is, the number of tabs are higher than the number which fit in within the physical width of the screen).
1. I use ctrl-tab and ctrl-shift-tab to move the focus forth and back in the row of tabs. But I have not found an answer to how I can reach the end or beginning of the row. Is there a keyboard shortcut to achieve this?
2. I should also like to know if there are keyboard shortcuts for moving a tab that is in focus to the left or the right. I have tried the shortcuts I know from other programs but none of them seem to work.

1. No, you would need to add a user defined command (actually: two) with a "script" for which you can assign keyboard shortcuts then
Select first tab: seltab 1;
Select last tab: seltab -1;

2. Same as in 1.
Move tab to the left: #1044;
Move tab to the right: #1045;
