Testcase:

In ~/.xbindkeysrc:
  "xterm &"
       XF86LaunchA

In ~/ov.xkb:
  xkb_keymap {
      xkb_keycodes { include "evdev" };
      xkb_types    { include "complete" };
      xkb_compat   { include "complete"
          interpret Overlay1_Enable+AnyOfOrNone(all) {
              action= SetControls(controls=Overlay1);
          };
      };
      xkb_symbols  { include "pc+inet(evdev)+us"
          key <INS> { [ Overlay1_Enable ] };
          key <AE01> { overlay1 = <AE02> }; // Insert+1 => 2
          key <TLDE> { overlay1 = <I128> }; // Insert+~ => XF86LaunchA
      };
      xkb_geometry { include "pc(pc104)" };
  };

Apply this layout: 'xkbcomp ~/ov.xkb $DISPLAY'.
Run "xbindkeys -n -v"
In the exact order:
- press Insert
- press Tilde
- release Insert
- wait
- release Tilde
Keyboard input in the new terminal window(s) would be locked
until another Insert+Tilde .
