How to scroll a view in a ECL (RCPTT) script ?

Question

In one of my tests, written in ECL with RCPTT, I need to check the value of a register. To do so I check the value shown in the registers view

The problem is that the register I'm looking for is far in the list. And the debugger load the value dynamically, when scrolling the list.

57-data-list-register-values --thread 1 --frame 0 x 15
57^done,register-values=[{number="15",value="0x0"}]
(gdb) 
58-data-list-register-values --thread 1 --frame 0 N 15
58^done,register-values=[{number="15",value="0"}]

So in order to check the value of my register, I need to force a scrolling to force the debugger to load the value. So here's my question : how can I make the test scroll the view ?

---

If I don't do this, the execution fail when I try to select the register using this:

get-view Registers | get-tree | get-item "General Registers/MY_REGISTER"

It throws me:

Failed to set selection: [[General Registers, MY_REGISTER]].

I've tried to use expand-all to force the discovery but it didn't worked.

If there's keyboard control in that grid, you can first focus on one of the rows (like, click on the top row with some fixed coordinates, or maybe just click viewname is enough), and then key-type PageDown or key-type Down several times.
