You may redefine all the keys and the time step with predefined macros. The
author provided the following able:
```
Control Description Default Key
------- ------------------------- -----------
IT Increase throttle XK_Page_Up
DT Decrease throttle XK_Page_Down
FD Move stick forward XK_Up
BK Move stick back XK_Down
LT Move stick left XK_Left
RT Move stick right XK_Right
CS Center stick XK_Enter
```
There is another macro, `dt`, which is the time step. See some important points
on this in the author's comments in the [Alternate Build
Instructions](#alternate-build-instructions) section.
If however you wish to change the above controls, see the header file
[keysym.h](keysym.h) for the definitions of other characters that you might wish
to use. The name of the macro in the header file is what you need to set the
macros to, depending on what controls you wish to redefine. For instance, to set
the throttle up and down to `u` and `d`:
```sh
make clobber IT=XK_u DT=XK_d all
```
because in the header file you can see that `XK_u` corresponds to `u` and `XK_d`
corresponds to `d`:
```c
#define XK_d 0x0064 /* U+0064 LATIN SMALL LETTER D */
#define XK_u 0x0075 /* U+0075 LATIN SMALL LETTER U */
```
Note that the [keysym.h](keysym.h) file is not complete from X11; it's just the
more likely candidates (and some that are probably unlikely :-) ).
The upper case letters would be `XK_U` and `XK_D` and you can search the header
file for 'LATIN CAPITAL D', for example.
For those who do not have a Page Up or Page Down key, see [alternate

The keys were somewhat arbitrarily selected but it was decided to make them both

### Alternate build:
As the Makefile allows you to configure the keys to use you may redefine the
keys. This can be done for both versions but if you don't have certain keys it's
even more important. In the main program increasing throttle is by page up and
decreasing throttle is page down. In the alt build it is `f` and `d`
respectively as these are letters on the left side of the keyboard which is
easier to use if one is using the right side for movement.

In the alt build it is `f` and `d` respectively as these are letters on the left
side of the keyboard which is easier to use if one is using the right side for
movement. These are hard coded, as noted.
To use the default settings for the alternate build:
```sh

for the definitions of other characters that you might wish to use. The name of
the macro in the header file is what you need to set the macros in the Makefile
to, depending on what controls you wish to redefine.
You may change the other keys as described in the build instructions, above, but
this alt code can be seen as an alternative for those who don't have or don't
want to use page up and page down.
For instance if you want to use 'u' to increase throttle and 'd' to decrease
throttle you would do:
```sh
make clobber CDEFINE="-UIT -UDT -DIT=XK_u -DDT=XK_d -DUP=XK_Up -DDN=XK_Down -DLT=XK_Left -DRT=XK_Right \
-DCS=XK_Return" alt
```
because in the header file you can see that `XK_u` corresponds to `u` and `XK_d`
corresponds to `d`:
```c
#define XK_d 0x0064 /* U+0064 LATIN SMALL LETTER D */
#define XK_u 0x0075 /* U+0075 LATIN SMALL LETTER U */
```
Note that you must specify all keys and other `-D` macros if you redefine any of
them.
The upper case letters would be `XK_U` and `XK_D` and you can search the header
file for 'LATIN CAPITAL D', for example.
See [alternate build instructions](#alternate-build-instructions) for the proper
macro names. You may do the above for the entry itself as well, of course, if
you do not like the defaults selected.
