 +to the Keymapper with CNTL+F1, the problem may be associated with your Window Manager.
  
 +The solution is to look at:
 +APPLICATIONS MENU -> SETTINGS -> WINDOW MANAGER -> KEYBOARD TAB then scroll down until you see workspace_1,
 +workspace_11, workspace_12, and delete those assignments. If you wish to enable those again, just use RESET to Default.
 +
 +This allows DOSBox to use CNTL+F1, CNTL+F11, and CNTL+F12 to access the Keymapper and Change the CPU Cycles accordingly.</note>\\

 +Start DOSBox from the Slackware Xfce menu: APPLICATIONS MENU → SYSTEM → DOSBox
 +
 +DOSBox will come up and you will be on Drive z:
 +Type the following commands adjusting for the specific Emulator.
 +<code>mount c ~/path/to/subdir/TRSDOS
 +c:
 +dir /p
 +trs80 MMCPM321.DSK</code>\\ 
 +
 +I copied the Monetzuma Micro CP/M DSK file into the TRSDOS subdirectory. I could have just used trs80, and then immediately used <key>F9</key>\\ 
 +to select the Drive, and the OS used on that drive, and then used <key>F10</key> to read the Disk's information and reset the Emulator.\\ 
 +Use <key>CNTL</key>+<key>F12</key> to increase cycles to around 9K or 10K so the DIR B: command in CP/M, or the DIR :0 command in\\ 
 +TRSDOS acts like a real TRS-80 Model 4.
 +
 +Montezuma Micro ver 2.3.1 will come up running.
 +
 +Floppy Disk formatting a disk takes about 30 seconds, and booting up is less than 30 seconds with a 2 MHZ CPU with 64 or 128 Meg RAM.
 +
 +Use <key>F9</key> to configure another DSK file to view in Drive :1\\ 
 +Use <key>F10</key> to RESET the System\\ 
 +
 +Use PIP to transfer a couple of files to Drive M:. (pip destdrive:=sourcedrive:filename.*)\\ 
 +<code>pip m:=a:mdm730*.*</code>
 +
 +<key>F1</key> does a DIR A:  - ONLY in Montezuma Micro CP/M\\ 
 +<key>F2</key> does a DIR B:  - ONLY in Montezuma Micro CP/M\\ 
 +<key>F3</key> does a DIR M:  - ONLY in Montezuma Micro CP/M\\ 
 +
 +Reference the Command Summary above for more commands.
 +
 +Now, the whole world of CP/M, TRSDOS, LDOS, NEWDOS is available for your work or play. Be sure to check out DUP, and CONFIG, in\\ 
 +Montezuma Micro CP/M, and all the other utilities with CP/M and TRSDOS. With Config you can read and write almost any format available\\ 
 +at that time.
 +
 +When you are finished with the Emulator use <key>SHIFT</key>+<key>F10</key> to exit. Then you need to un-mount the subdirectory, and exit the Terminal Window.\\ 
 +Here are the commands
 +<code>z:
 +mount -u c
 +exit</code>\\ 
 +
 +
 +If DOSBox doesn't terminate properly, open another Terminal Window and use the top command to find the DOSBox process ID Number.\\ 
 +Assume 4790. Use q or CNTL C to stop the top command and then use kill -9 4790 to terminate DOSBox.
 +<code>top
 +q</code>\\ 
 + 
 +<note> <key>CNTL</key>+<key>c</key>  --  Can also be used to Terminate the command "top"</note>\\ 
  
 +<code>kill -9 4790</code>\\
