+# Description: Toggle mount of MTP device (eg. Android device)
+#              'l' to list mountable devices
+#              'n' integer associated to device to mount
+#              'q'/'Return' exit
+#
+# Notes: The MTP device should be mounted at /run/user/$UID/gvfs.
+#        Put /run/user/$UID/gvfs to bookmark entries (NNN_BMS) for faster access.
+#        Make sure the device is unlocked when mounting.
+#
+#        When doing copy-paste into MTP device, you will get an error like this:
+#            cp: preserving times for './gambar1.png': Operation not supported
+#        That just means the file is copied but timestamp won't be preserved.
+#        It's like doing `cp -p localfile.txt file-to-SMB.txt`.
+#
+# Dependencies: gvfs-mtp
+#
+# Shell: POSIX compliant
