+**Tip: use Begin/BeginChild to put yourself into the context of another window prior or after outputting to it**<br>
+https://github.com/ocornut/imgui/issues/270
+
+An interesting trick that isn't obvious is that you can use Begin() just to put yourself into the context of that window. So here I want to react to the user inputting an address to scroll to, I use BeginChild() again on the child that I've already drawn so I can use SetScrollFromPosY() on it.
+
+```
+ImGui::BeginChild("##scrolling", ImVec2(0, -ImGui::GetItemsLineHeightWithSpacing()));
+// ...(draw main content)
+ImGui::EndChild();
+
+// And then much later in the main window, get back into child context to change scrolling offset
+ImGui::BeginChild("##scrolling");
+ImGui::SetScrollFromPosY(ImGui::GetCursorStartPos().y + (goto_addr / Rows) * line_height);
+ImGui::End();
+```
