Research direction

Start in runtime/src/js/pgadmin.js at launchPgAdminWindow and compare its input handling with the zoom roles assembled in runtime/src/js/menu.js. Run the Electron desktop build and verify that Ctrl plus numpad +, -, and 0 work alongside the existing main-keyboard shortcuts; the report has only been tested on Linux Wayland.

Description

Bug

i build pgadmin4 locally on linux, as Electron desktop, from source; it builds/installs ok

Version 9.18
Application Mode Desktop
Commit ecb6446c313b69ec1310b5816178e79040f98a92 (2026-10-02 17:41 +0100)
Python Version 3.14.7
Electron Version 44.4.5
Browser Chrome 152.0.7977.130
Operating System Fedora Linux 44 (Forty Four), Linux-7.2.8-200.fc44.x86_64-x86_64-with-glibc2.43

rpm -qa pgadmin4-electron
  pgadmin4-electron-git_master-0.20261004_135416.gitecb6446.fc44.x86_64

on exec of the Desktop runtime,

-- Ctrl + main-keyboard + (=), - and 0 zoom in, zoom out and reset as expected
-- UI View > Zoom In / Zoom Out / Actual Size work from the menu

BUT,

-- Ctrl + numpad +, Ctrl + numpad - and Ctrl + numpad 0 do nothing

checking src,

runtime/src/js/menu.js:169-171

    { role: 'resetZoom' },
    { role: 'zoomIn' },
    { role: 'zoomOut' },

builds the View menu zoom items from Electron menu roles.

electron v44.4.5 hardcodes those roles' accelerators in lib/browser/api/menu-item-roles.ts

resetzoom: accelerator: 'CommandOrControl+0'     (line 169)
zoomin:    accelerator: 'CommandOrControl+Plus'  (line 238)
zoomout:   accelerator: 'CommandOrControl+-'     (line 246)

electron v44.4.5's accelerator parser, shell/common/keyboard_util.cc, maps those only to main-keyboard keys.
numpad keys are SEPARATE key codes, reachable only through separate tokens; e.g.:

"plus"   -> ui::VKEY_OEM_PLUS   (line 97, main keyboard)
"numadd" -> ui::VKEY_ADD        (line 88)
"numsub" -> ui::VKEY_SUBTRACT   (line 93)
"num0"   -> ui::VKEY_NUMPAD0    (line 78)

since menu items hold only ONE accelerator, role items can't be edited to ALSO match a numpad key.

a workaround/fix is to handle numpad keys directly in the main window with a before-input-event handler, matched on input.code.

e.g., this works

+    } else {
+      return;
+    }
+    event.preventDefault();
+  });
+
   setupMenu(pgAdminMainScreen, configStore, menuCallbacks);

   setupDownloader();

with that patch/build, Ctrl- +/-/0 work BOTH on main keyboard AND numpad.

i've only tested this on Linux/KDE Plasma/Wayland
NOT tested on X11, Windows or macOS.

but iiuc the role accelerators are the same on all platforms, so i'd expect the same behavior on those.
