Hello,

FYI:

Q. TSE: Key: Assignment: Which key is used for 'Select all' according to IBM CUA guide lines?

Note: TSE follows in general also the IBM CUA guide lines.

AI Overview

According to the IBM Common User Access (CUA) guidelines, which
established many modern keyboard standards, the shortcut for Select All
is generally Ctrl + A (Control + A).

While early IBM CUA (circa late 1980s) introduced different shortcuts
for actions like Cut, Copy, and Paste (Shift+Del, Ctrl+Ins, Shift+Ins),
the Ctrl+A mapping for "Select All" became part of the standard set of
keystrokes that defined GUI interaction.

Key Aspects of CUA Shortcuts:

Select All: Ctrl + A.

Other Standardized Shortcuts: Ctrl + X (Cut),
                              Ctrl + C (Copy),
                              Ctrl + V (Paste),
                              Ctrl + Z (Undo), which were
                              adopted from earlier graphical systems.

Object-Action: CUA promoted an "object-action" model, where an item is
               selected first (using Ctrl+A to select all), and then an
               action is applied.
