# Disabling auto text copying

If you select text by mouse, it is copied to the clipboard at the same time. To disable the auto text copying, edit the AutoTextCopy line in the [Tera Term] section of the setup file like the following:

    AutoTextCopy=off

    Default:
    AutoTextCopy=on

# Delimiters of a word selected by double clicking

You can select a word by double clicking it with the left mouse button. You can specify delimiter characters for the word selection by editing the DelimList line in the [Tera Term] section of the setup file like the following:

    DelimList=<delimiter characters>

For example:

    DelimList=<>()[]

specifies 6 delimiter characters "<", ">", "(", ")", "[" and "]". Note that the space and "$" characters should be specified as "$20" and "$24":

    DelimList=$20    ; space character

    Default:
    DelimList=$20!"#$24%&'()*+,-./:;<=>?@[\]^`{|}~

In the DelimList line, only singe-byte code characters can be specified. Double-byte code characters (Japanese kanji) are regarded as delimiters. You can make them be non-delimiters by editing the DelimDBCS line like the following:

    DelimDBCS=off

    Default:
    DelimDBCS=on

If you prefer the word selection behavior of earlier Tera Term versions, specify like the following:

    DelimList=$20
    DelimDBCS=off

# Disabling the pop-up menu

When the menu bar is hidden, clicking the left mouse button while pressing the Ctrl key causes the pop-up menu to appear. To disable the pop-up menu, edit the EnablePopupMenu line in the [Tera Term] section of the setup file like the following:

    TitleFormat=5

# Actual colors of "white" and "black" colored text

The escape sequences "<ESC>[37m" and "<ESC>[30m" make the text color white and black, respectively. Similarly, the escape sequences "<ESC>[47m" and "<ESC>[40m" make the background color white and black, respectively.

Some applications assume that the screen background is black (like real VT100 terminal), and expect that white colored text is visible. However, when the background color of Tera Term is white, therefore white colored text is invisible.

If you edit the UseTextColor line in the [Tera Term] section of the setup file like the following:

    UseTextColor=on

the actual color of "white" colored text (background) becomes a color for "Text" specified in the [Setup] Window dialog box. Similarly, the actual colors for "black" text (background) becomes a color for "Background".

    Default:
    UseTextColor=off

# Space between characters (lines)

To change space between characters (lines), edit the VTFontSpace line in the [Tera Term] section of the setup file like the following:

    VTFontSpace=<dx1>,<dx2>,<dy1>,<dy2>

    Where:
      <dx1>  Left side space for each character in pixels.
      <dx2>  Right side space for each character in pixels.
      <dy1>  Space above each line in pixels.
      <dy2>  Space below each line in pixels.

    Example:
    VTFontSpace=0,1,0,0    1 pixel of right side space for each character.
    VTFontSpace=0,0,1,0    1 pixel of space above each line.

    Default:
    VTFontSpace=0,0,0,0

# Hiding the [Window] menu

To hide the [Window] menu, edit the WindowMenu line in the [Tera Term] section of the setup file like the following:

    WindowMenu=off

    Default:
    WindowMenu=on

# How to scroll the screen when the window size is maximized

The screen scrolling method can be specified when the window size is maximized.

When the window size is maximized, the screen will be corrupted while the screen is scrolling as same normal window. So, a user can change the method of scrolling method.

- Method 0. Normal scrolling method is used. However, a part of character will be corrupted while scrolling.
- Method 1. Scrolling method until Tera Term 4.94 is used. Character is not corrupted, however the screen flickers and the scrolling speed is slow.
- Method 2. New method since Tera Term 4.95 is used. The screen does not flicker, however bottom line will remain garbage on scrolling back.

The default value is Method 2 when the window size is maximized. If you have a problem by using scrolling, the method can be changed another method.
For example, when the MaximizedBugTweak entry of [Tera Term] section is changed below setting, the Method 1 is used for scrolling.

    MaximizedBugTweak=1

    Default:
    MaximizedBugTweak=2

# Display the cursor even if the window comes out of focus

Tera Term will display the cursor even if the window comes out of focus.
If you want to disable this option, modify a line of KillFocusCursor in [Tera Term] section of setup file as follows.

    KillFocusCursor=off

    Default:
    KillFocusCursor=on

# Fix the initial window position

In order to change the default window position, change values of VTPos line(VT Window) and TEKPos line(TEK Window) at [Tera Term] section inside the setup file.
For example, if you want to set the default VT window position to 200 pixels from the left side of the screen and 100px from the top of the screen, change the setup file as follows.

    VTPos=200,100

The initial position is not fixed and Windows can decide the position by changing the setup file as follows.

    VTPos=-2147483648,-2147483648
    TEKPos=-2147483648,-2147483648

Notice: As described below, if SaveVTPosWinPos is on and at the time of executing "Save setup" or closing VT window, VTPos setting will be overwritten by current window position setting.

    Default:
    VTPos=-2147483648,-2147483648
    TEKPos=-2147483648,-2147483648

# Save the window position

Tera Term does not save the window position when "Save setup" was called.
If you enable this position, current window position is saved to a specified setup file.

Also if this option is enabled, current window position and terminal size are saved to the current setup file when VT window was closed.

    SaveVTWinPos=on

    Default:
    SaveVTWinPos=off

# Change the window icon

Tera Term executable program includes "VT window" icon, "TEK window" icon, and some other icons. If you change the value of VTIcon or TEKIcon, the displaying icon of VT window or TEK window is changed.

For example, to use old icon for VT window, specify like the following:

    VTIcon=VT_CLASSIC

Following icon names are available:

Icon name | Icon
--- | ---
TTERM |
VT |
TEK |
TTERM_CLASSIC |
VT_CLASSIC |
TTERM_3D |
VT_3D |
TTERM_FLAT |
VT_FLAT |
CYGTERM |
Default | Default("VT" at VT window, "TEK" at TEK window)

Also, the icon of SSH connection can be changed. For example, when the yellow icon(TTSSH2.62 earlier) is specified, please change the SSHIcon entry in the [TTSSH] section in the following:

    SSHIcon=yellow

The SSHIcon can be specified in the following names:

Name | Icon
--- | ---
flat2 |
classic |
yellow |
green |
flat |
Default | A default icon(equal to flat2)

    Default:
    VTIcon=Default
    TEKIcon=Default
    SSHIcon=Default

# Delay for stating of text selection

You can configure the delay for the start of text selection with the mouse and treat it as a click if the time you drag with the mouse is short.
For example, to handle as a click when the mouse drag time is shorter than 200 msecs, edit the MouseSelectStartDelay line in the [Tera Term] section of the setup file like the following:

    MouseSelectStartDelay=200

    Default:
    MouseSelectStartDelay=0

# Don't round window corners

On Windows 11 the corners of window are rounded, so some areas are not shown. To prevent rounding the corners of the VT and TEK window, change the WindowCornerDontround line in [Tera Term] section of the setup file like the following:

    WindowCornerDontround=on

    Default:
    WindowCornerDontround=off
