Font
Here, display of ASCII characters (0x20～0x7F) is set. As of other characters, they are specified by “terminal” tab.
Caret
Caret is cursor for character entry. Traditionally, it was only blinking quadrangle, but in Poderosa, caret by graphics with beautiful animation is supported.
Character Transition
Transition is setting which decide what kind of graphic effect is used when characters are displayed or disappear. Fade in and out is an effect which gives change of brightness, zooming in and out is an effect which changes size of characters.
What kind of effect is adequate, it differs by performance of computer and by each user’s preference, so please first try some settings and select you like. As for adding new effects, if you have any idea, please inquire using feedback tool.
Background Image
Background image of terminal can be set. Some images incorporated in Poderosa plus images such ads arbitrary png, jpg can be specified. For instance, if different background images between staging server and production server is set in advance, it will contribute to avoid serious trouble caused by misrecognition of connection destination.
Tranparency of Background
If background image bothers display of character, it is putting the cart before the horse, so please set proper visibility. If original image is a little brighter, 20 % of visibility is adequate. If image is dark, from 50% to 100% is acceptable.
Terminal
Of settings related to terminal, one in common in all connection is included. As for one whose setting can differ by each connection, please refer to terminal setting of each connection.
Font of Non-ASCII Characters

Uses switching screen effect at the time of entering App mode
App mode is, in program started from shell, one which occupies screen (less, vi, emacs, and so on).
At the time of switching this, specifies if effect on screen is added.
Saves Session Constitution on Finish
When Poderosa is finished, specifies if connection destination information and tab constitution is saved and restored in the next start. Off course, at the time of restart, pass phrase input of SSH key can’t be saved, connection itself can’t be restored. Only restores to tab constitution.
If you use the same connection destination every day, please check, if you use different connection destination each day, it is recommended not to check.
The Amount of Scroll Lines by Mouse Wheel
In order to see those are hidden in upper side of screen, specifies amount of scroll.
In App mode, mouse wheel send data to server judging that it is same as upper and lower cursor keys, it also specifies how many cursor keys.
IME Box Display Key Allocationて
In case Japanese or Chinese is directly input via IME, inputs from popup dialog.
Here, shortcut key for starting this dialog is specified.
The Interval of Flickering of Standard Caret
Specifies the interval of flicking in case of caret of quadrangle or underscore. As for animation caret, because interval differs depending on making of the animation, this setting isn’t applied.
Line Feed Effect Time
For instance, if starting of a new line is conducted on the bottom line of screen in shell, whole screen scrolls by one line. Specifies needed time in this effect.
Network
As for character string of connection destination, it is connected after IP address is resolved in DNS, priority degree setting of IPv4/v6 is conducted. At the time of connection, if it’s via SOCKS, it is specified. SOCK’s version is limited to be only 5. Setting and tool related to SSH. It’s specified how much time passes before sending keep alive. Because standard is passed time from final input, if input is continuous, keep alive isn’t executed. And if 0 is specified, keep alive won’t be sent. Existence of message display related to check of server’s public key is specified. It’s rare that it’s required to seriously check server’s public key, but in SSH protocol specification, confirmation if hash of public key is the same as one separately obtained should be conducted by user himself or herself. If malicious third party camouflages server, this hush is different from intended one. A new SSH key can be made by GUI. It’s the same function as ssh-keygen command of OpenSSH. Specifies the number of connection destination history held inside. Poderosa extracts pull-down candidate of connection destination or account name from one existing in history. In Start menu, one used more recently of connection destination history is selected and shown. Here, the number to be shown is specified. Please select adequate number which suites usual using condition or screen size used. Although as for secret key used in the past, selection is easy because it is pull-down display, the number of pass memorized is specified. Deletes each history. Before execution, it is via confirmation message box.

Plus, it’s impossible to switch yes or no of using SOCKS, only setting common to all.

The Number of Holding Connection Destination History
If it’s too big, size of setting file becomes big, or security risk in case in which the setting file is leaked to outside becomes high. If it’s too small, there is trouble because input is necessary even if it is connection destination previously used.The Number of Connection Destination Shown in Start Menu
